What is the minimum bandwidth AM signal that can betransmitted and still convey all the necessary intelligence
In Amplitude Modulation, upper frequency is often limited too 5kHz.
So, minimum bandwidth beacoms 10KHz.
So, AM signals should be at least 10KHz apart to transmit necessary information.

Problem 3) Design a Double-Side-Band (DSB) based transmitter and receiver (find minimum bandwidth requirement and draw the block diagrams) to send and fully recover 10 human-voice type signals with each signal having the bandwidth of 5kHz. Note that the receiver needs at least 3kHz of separation between each DSB signal for full recovery and you are limited to use AM radio frequency spectrum of 540 to 1600 kHz.
