WebAlternatively, the frequency of the sinusoids in a sinusoidal model may be altered directly, and the signal reconstructed at the appropriate time scale. Transposing can be called frequency scaling or pitch shifting, depending on perspective. For example, one could move the pitch of every note up by a perfect fifth, keeping the tempo the same. Web4 aug. 2024 · I'm trying to plot a sine wave whose frequency decreases linearly over time (amplitude stays the same). This is my code: Theme Copy clear all; close all; clc period = 0.08; for x = 0:4/1000:2 a = 5; b = ( (2*pi)/ (period + 0.001)); c = 300; d = 30; c = c * -1; output = a.*sin (b.* (x+c))+d; plot (x, output, 'Linewidth', 2); end
