Frequency Selective Circuits

Q2: (a) Derive the expression for H(s), where H(s) Vo/Vi, for the lowpass filter. (b) At what frequency wi the magnitude of H(jw) be maximum? (c) What is the maximum value of the magnitude of H(jw)? (d) At what frequency will the magnitude of H (j) equal its maximum value divided by 2? (e) Assume a resistance of 10 k2 is added in parallel with the 100 nF capacitor in the circuit. Find we, H(j0), H(j), H(j0.1w) and H(j10wc) R
