What are the differences between AM FM and PM?

AM transmitters and receivers are less complex than FM and PM, but synchronization is needed in the case of SSBSC carriers. FM (or PM) transmitters are more complex than AM because the variation of modulating signal has to be converted and detected from the corresponding variation in frequencies.

Why do we use FM over PM?

Answer: FM has higher bandwidth, due to which it is less affected by noise interference. Hence, the signal quality of FM is better than PM.

Which is best AM or FM?

FM has better sound quality due to higher bandwidth. AM radio ranges from 535 to 1705 KHz (OR) Up to 1200 bits per second. FM radio ranges in a higher spectrum from 88 to 108 MHz. (OR) 1200 to 2400 bits per second.
