Hi, i've been asked today few questions but i were suspecting of the answers
1. what is the difference between RC circuit and RC with an op-amp ? i said the gain , he said suppose its 1 , he answered that in the RC-op-amp the capacitor will charge lineary , is this correct ??
2. what's the difference between butterworth and cheybychev filters ?
3. what happens when there are ripples in a low pass filter circuit in the pass band area ??
