The longest National Highway is the NH7, which runs between Varanasi in Uttar Pradesh to Kanyakumari in Tamil Nadu, at the southernmost point of the Indian mainland, covering â¦a distance of 2369 km, and passes through Hyderabad and Bangalore.
PCM (Pulse Code Modulation): a system for representing a sampled signal as a series of multi-bit words. This is the technology used in audio CDs. PDM (Pulse Density Modulation): a system for representing a sampled signal as a stream of single bits. Sampling rate is the rate at which a signal is sampled to produce a discrete-time representation. Wordlength is the number of bits used to represent a sample.
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).
