Introduction to Pulse Width Modulation. A look at a powerful technique for controlling analog circuits with a microprocessor's digital outputs. Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor's digital outputs. PWM is employed in a wide variety of applications, ranging from measurement and communications to power control and conversion.
From Wikipedia, the free encyclopedia. Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of possible required time-shifts. This is repeated every T seconds, such that the transmitted bit rate is bits per second. complete PPM frame is about 22.5 ms (can vary between manufacturer). Signal low state is always 0.3 ms. It begins with a start frame (state high for more than 2 ms). Each channel (up to 8) is encoded by the time of the high state (PPM high state + 0.3 x (PPM low state) = servo PWM pulse width).
