Question

1. a) An audio signal contains frequencies from 32 Hz to 16.0 kHz. i) What is the baseband bandwidth of this signal? ii) Explain briefly how this audio signal can be modulated to produce an Amplitude Modulated (AM) radio frequency signal. iii) What would be the bandwidth of this modulated signal? iv) Assuming that each AM radio station requires a 'guard' band of 0.1 kHz, how many broadcast amplitude modulated radio stations would be available in the AM band (540 kHz to 1600 kHz)?

Step 1

In this case, it is from 32 Hz to 16.0 kHz. ii) To produce an AM radio frequency signal, the audio signal can be modulated by varying the amplitude of a carrier wave with a frequency in the radio frequency range. This is done by multiplying the audio signal with Show more…
