This is not a HW question but an activity i am working on. The attachment is a symbolic AM transmitter. The carrier is 15MHz and message frequency is 2Mhz. I want to sketch the waveforms labelling them in as much detail as possible. Also sketch the output waveform in both time and frequency domains and calculate its bandwidth (a paint rough drawing would be helpful) If the signal was alternated with a 2kHz tone every 0.25s, sketch output waveform in both time and frequency domain and calulate its bandwidth. Repeating this with commercial speech replacing the message tone.
