The following is a circuit that forms a sine wave into a square wave. Can you give me the specific values and models of each resistor and triode? Input is 10V, 20K frequency.
The first two op amps play the role of attenuation, that is, the waveform enters the first two op amps and finally gets a relatively small value, such as 5V. Finally, compare the voltages with a comparator and output a square wave! The resistance parameters of the first two operational amplifiers can be the same! Also, you have to have a square wave output amplitude value, so as to give the circuit!
