WebApr 24, 2012 · But you need at least two samples per cycle (2*pi) to depict your sine wave. Otherwise you'll get an alias frequency, and in you special case the alias frequency is infinity as you produce a whole multiple of 2*pi as step size, thus your plot never gets its arse off (roundabout) zero. Using Rick's code you'll be granted enough samples per period. WebMar 7, 2016 · variable sine wave with fixed number of periods.

The spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar time-domain waveform, and the two versions are mathematically related by the Fourier transform. The spectrum is of particular interest when pulses are subject to signal processing. For example, when a chirp pulse is compressed by its matched filter, the resulting waveform contains not only a mai… cindys rooftop brunch menuWebMay 8, 2024 · It looks like you misread some parameters of chirp usage, particularly target frequency and target time. When you work with a swept cosine sweep, target frequency will be reached at half of target time.
