WebFeb 23, 2024 · Create a new App Designer app by selecting "App Designer" from the MATLAB Home tab. Drag and drop an axes component onto the app design canvas. Add the following code to the app's startup function to initialize the axes and create a line object for the sine wave: Webwhere: c k [ ] is the cosine wave for the amplitude held in ReX[k], and s k [ ] is the sine wave for the amplitude held in ImX[k].For example, Fig. 8-5 shows some of the 17 sine and 17 cosine waves used in an N = 32 point DFT. Since these sinusoids add to form the input signal, they must be the same length as the input signal. In this case, each has 32 points …
