What is PAM PPM and PWM?
PAM is an abbreviation for Pulse Amplitude Modulation. PWM is an abbreviation for Pulse Width Modulation. PPM is an abbreviation for Pulse Position Modulation. These are the types of pulse modulation.
What is pulse modulation used for?
Pulse modulation methods are used to transfer a narrowband analog signal, such as a phone call, over a pulse stream. Some schemes use a digital signal for transmission, making them essentially an analog-to-digital conversion.
