Frequency Modulation and Phase Modulation: From the purely theoretical point of view, the difference between FM and PM is quite simple—the modulation index is defined differently in each system. However, this is not nearly as obvious as the difference between AM and FM, and it must be developed further. Circuit Skills PWM Pulse Width Modulation Pulse Width Modulation is an easy method for controlling analog devices with a digital signal. It is a great way to control LEDs, lamps, motors, and more. Power line communication Basics. Power line communications systems operate by adding a modulated carrier signal to the wiring system. Different types of power line communications use different frequency bands. Since the power distribution system was originally intended for transmission of AC power at typical frequencies of 50 or 60 Hz, power wire circuits have only a limited ability to carry higher frequencies.
