Question

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.
