Other examples of continuous signals are sine wave, cosine wave, triangular wave etc.
2.
One phase is attached to a potentiostat which is set to zero volts, while the other potentiostat is driven with a triangular wave.
3.
Thus the shape of a harmonic of a sinusoidal wave form will be sinusoidal and the shape of a harmonic of a triangular wave form will be triangular.
4.
:: Anatomical reasons : The vocal cords in themselves produce a reedy sound, rich in overtones, something like a square or triangular wave ( not sure which ).
5.
If " E " i is a sine wave, triangular wave, or wave of any other shape that is symmetrical around zero, the zero-crossing detector's output will be square.
6.
The most basic way of creating the PWM signal is to use a high speed comparator ( " "'C "'" in the block-diagram above ) that compares a high frequency triangular wave with the audio input.
7.
The issue I have is that I can't convince myself that g ( x ) = sin ( x )-for all I know it might be a triangular wave . . . My attempts at solving this fail-I get various formula that might give values for pi-but I was looking for something more solid.
