The connection and differences between FM modulator and FM transmitter

Summary:
1. An FM modulator and an FM transmitter are both necessary to transmit an FM signal
2. An FM modulator modifies the FM signal based on the input signal while the FM transmitter is responsible for sending out the signal to the air
3. In a system, the FM modulator appears before the FM transmitter
4. The FM modulator determines at what frequency the system transmits at while the transmitter is responsible for the power level and the range More →
