Law of sines: the ratio of the length of a side of a triangle to the sine of its opposite angle is constant. Using the law of sines makes it possible to find unknown angles and sides of a triangle given enough information. Where sides a, b, c, and angles A, B, C are as depicted in the above calculator, the law of sines can be written as shown below. Thus, if b, B and C are known, it is. (1990).

Gopakumar. ← Video Lecture 9 of 37 →. triangle-to-sine waveshaper: the upper section is a very precise triangle-to-sine converter (thank's to tim stinchcombe who recommended this circuit). it can be used to convert any triangle waveform into a (nearly) perfect sine. the converter is much better than the simple diode converter used in the a-110-1, a-111-1, a-145 and a-147-2. two trimming potentiometers are used to optimize the sine. In the design of signal generators, the need arises to convert a triangular wave to a sine wave . The VTC of a triangle-to-sine converter is shown in Fig. P1.57a for the case in which and . have the same slope at the origin. In this case one can readily prove that the peak values of the two waveforms are related as = (π/2) . For right angled triangles, the ratio between any two sides is always the same, and are given as the trigonometry ratios, cos, sin, and tan. Trigonometry can also help find some missing triangular information, e.g., the sine rule

Order NowI only need the calculations for the problem. There are two methods for designing the nonlinear triangle-to-sine converter. 1. Assume the maximum value of the sine wave is 1.2V (two diode potentials using the constant-voltage model of a silicon diode). Match the slope of the triangle wave v tri (q) to that of the sine wave v s (q) at q = 0; this allows you to compute the maximal value. Triangular edges (implying slew rate limitations) and not getting full (i.e down to zero) output amplitude suggests to me that the transistors aren't being driven hard enough - especially given the ~30 mA peak collector current set by R14. This configuration is a differential amplifier, amplifying the difference between the (fixed) voltage at the base of T4 (on the right) and the AC voltage. Re: Convert sine to sawtooth. 02-25-2016 03:55 PM. You could use the increment method I suggested for sawtooth except that you increment when the square (or sine) wave is positive and decrement when negative. This method does not depend on the quality of the input signal except at the comparator transitions View tri2sin.pdf from ECE 20800 at Purdue University. 39 EXPERIMENT 3 Triangle to Sine Converter Design Acronyms I-V Current vs. Voltage Parameters Io diode reverse saturation current diode idealit Electronics (Triangle to Sine) (Price Negotiable) I only need the calculations for the problem.

A sine-wave, square-wave and triangle-wave are completely symmetrical. A full-wave rectified sine-wave is not symmetrical so would be difficult to convert into a triangle-wave. Add an offset voltage to a trangle-wave to make it completely positive A triangle is easy to generate simply by charging and discharging a capacitor with a constant current. It also isn't too far from a sine wave with only 12% distortion. Rather than simply filtering the triangle, it can be shaped. This is something illustrated by the late Hans Camenzind in his Designing Analog Chips book Design a triangle-to-sine converter and validate its performance with Multisim. Submit (a) your calculations, (b) hard copy of your Multisim schematic, (c)Multisim transient analysis shoving both the triangle input and ''sinusoidal'' output voltages, and (d) the results of Munising Fourier analysis showing THD.

What is the period of a sine cosine curve? The Period is how long it takes for the curve to repeat . The distance sound travels. In order to convert a sine wave into a square wave you only have no use an Opamp (like IC-741) using a non-inverting amplifier circuit with a very large gain. The very large gain willl make the circuit saturate quickly, transforming your sine into a square. This site has exactly what you need A description is given of MOS circuit design techniques for nonlinear analog circuits that perform a triangle-to-sine wave conversion. These techniques may also be applied to synthesizing other functions. Design techniques for compensating the conversion for variations in temperature, processing, and triangle wave amplitude are also presented Are you looking for a series expansion of arcsin(x)? The best I have seen to convert to radians is If sin(theta) = x, theta = arcsin(x) = approx x + (1/6) x^3+ (3/40. This circuit uses a diode to clip the top of an input triangle wave. Above 5.7 V, current flows through the diode and resistor and reduces the output voltage proportionally. Next: Triangle-to-Sine Converter Previous: AM Detector Inde
The crude triangle-to-sine converter of. can be improved considerably by rounding the sides of the triangular wave input, besides clipping it at the top and bottom. The circuit. provides a VTC with a slope of 1 V/V near the origin, where all diodes are off. As the magnitude of V T rises and approaches a diode drop, either D 1 or D 2 goes on, in effect switching R 2 into the circuit. At this. The log circuit (or diode circuit) is for the triangle to sine converter- distorting the triangle waves so they like more sine-y. They have nothing to do with making it oscillate. This is the core building block at work is a slightly more complex version of this: The comparator has a +/- output and some hysteresis. When it reaches the positive trigger point, it flips to high at the output. Answer to The crude triangle-to-sine converter of Fig. P10.33 can be...

I need to transform a bipolar sine wave (varies from -5 V to 5 V, 1 kHz) to a square wave for further digital processing (0 to 3.3 V), as in this image: The important thing is that this sine wave can't be distorted, so there can't be any limiting diodes at the input. I have got only 3.3 V and 5 V voltage supplies. An obvious way to go is an op. to digital converter, i.e. it converts a digital word to a corresponding analog voltage. The STM32 DAC module is a 12-bit word converter, with up to three output channels to support audio functions. The DAC can be used in many audio applications such as security alarms, Bluetooth® headsets, talking toys, answering machines, man-machine interfaces, and low-cost music players. The STM32 DAC can. In mathematics, the sine is a trigonometric function of an angle.The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).For an angle , the sine function is denoted simply as
The SIN function returns the sine of an angle provided in radians. In geometric terms, the sine of an angle returns the ratio of a right triangle's opposite side over its hypotenuse. For example, the sine of PI()/6 radians (30°) returns the ratio 0.5.
