It is an analog pulse modulation scheme in which the amplitude of train of carrier pulse are varied according to the sample value of the message signal. Jan 04, 2014 · I want to generate square pulse with different interval and the interval is random. in my case i have 1.2s 7 times,2.4s 7times and 3s 6times which will create 20 square pulse. the width is 0.07s. On this page, the Fourier Transform for the box function, or square pulse, is given. This page is pretty much a rehash of the page in the Fourier Transform theory section. The box function is a square pulse, as shown in Figure 1: Figure 1. The box function. In Figure 1, the function g(t) has amplitude of A, and extends from t=-T/2 to t=T/2. For ... Nov 21, 2019 · True Square waves are a special class of rectangular waves with 50% duty cycle. Varying the duty cycle of a rectangular wave leads to pulse width modulation, where the information is conveyed by changing the duty-cycle of each transmitted rectangular wave.
