A telephone line provides sufficient bandwidth (3 kHz) for intelligible voice conversations, but human hearing has a much higher bandwidth, typically
20 Hz to 20,000 Hz.
1. Design an active bandpass filter to mimic the bandwidth of a telephone line subject to the following constraints:
(a) Cascade a first-order active lowpass filter and a first-order active highpass filter,
(b) Set the corner frequencies to 300 Hz and 3.0 kHz,
(c) Set the passband gain to 0 dB,
(d) Choose resistors in the range 1.0 k to 100 k.
