In digital signal processing, upsampling, expansion, and interpolation are terms associated with the process of resampling in a multi-rate digital signal processing system. Upsampling can be synonymous with expansion, or it can describe an entire process of expansion and filtering (interpolation). When upsampling is performed on a sequence of samples of a signal or other continuous function, it produces an approximation of the sequence that would have been obtain… WitrynaImpulsive Metrics are properties related to the peaks of the signal. Peak value — Maximum absolute value of the signal. Used to compute the other impulse metrics. x …

WitrynaThe PRF is normally much lower than the frequency. For instance, a typical World War II radar like the Type 7 GCI radar had a basic carrier frequency of 209 MHz (209 million cycles per second) and a PRF of 300 or 500 pulses per second. A related measure is the pulse width, the amount of time the transmitter is turned on during each pulse. Witryna29 gru 2024 · The more input signal energy in the passband of each filter, the greater the output (amplitude or height on a frequency plot) for the FFT result bin representing that filter.
