I have to do a signal converter circuit for coursework.
This circuit should transform an sine wave input in a square wave, sawtooth wave and in triangular wave with same frequency, amplitude and Dc offset from the input
The sine wave input could has amplitude varing from o to 2, and it could have a +/- 5 DC offset.
To build this circuit I can use just Opamps, Transistors(Mosfet), and diodes.
In thought passing my input wave in a half-wave rectifier circuit and then pass it output in low-pass filter to get it offset. it works fine, for a 2V amplitude wave, but it fails for other amplitudes.
To transform the wave i use a high-pass filter to get the sine ana make it pass for a comparator, then i use a sommator and a inverter.It works ok for an 2V amplitude input.
To the triangular output I'm doing something similar( after the input I pass it throught a OpAmp integrator.
I haven`t tried the sawtoooth yet.
Hope someone can help me
