Speech signals typically contain frequencies from 300 Hz to 3300 Hz. In order to demodulate this baseband signal from its modulated waveform, a communication receiver front-end can be employed, which consists of a bandpass filter followed by a radio frequency down-converter. In this problem, you are asked to design a bandpass filter that can facilitate the demodulation of the modulated speech signal, which has a carrier frequency between 35 kHz and 40 kHz.
