Bandwidth of Signal and Transmission Medium

A massage signal of frequency $3 \mathrm{kHz}$  is used to modulate a carrier signal of frequency $1.5 \mathrm{MHz}$. The bandwidth of the amplitude modulated wave is

Channel bandwidth is measured in

What is channel bandwidth in communication?

Cellular Mobile works in the frequency range of _____.

The frequency band used for radar relay systems & T.V is

An audio signal consists of two distinct sounds: one a human speech signal in the frequency band of 200 Hz to 2700 Hz, while the other is a high frequency music signal in the frequency band of 10200 Hz to 15200 Hz. The ratio of the AM signal band width required to send both the signals together to the AM signal band width required to send just the human speech is:
