Hy ,
I have designed a Bandpass filter 400Hz to 2.4Khz with centre frequncy as 1Khz.The input is a 1Khz square signal. Although the circuit attenuates any signal out of the bandwidth i get a sinusoidal output(this is also justified by fourier transforms). But I need to get the same square wave as output.I use passive filters single pole with R and C. What modifications to get square wave as output ?
