Yesterday, I strolled around the Book City and accidentally found a very interesting book: Embedded Signal Processing Based on Embedded signal structure. First, it attracted attention because the processor involved was the DSP of the Blackfin series, which was rare. But I bo

length of 5, which delays two cycles on the timeline. X = zeros (1, 5) x (2) = 1 Sawtooth-generate sawtooth/triangular wave signals 1. The Sawtooth (t) function generates a sawtooth wave with a period of 2 pi for the time variable t, and the amplitude changes between + 1 and-1. 2. The Sawtooth (T, width) function generates a triangle wave on the time variable t. The width is the scale parameter of the value between 0 and 1, specifying the position of the peak of the sawtooth wave. The function
