Write an equation for the modulated signal, XFM (t). You can write your answer in terms of m (t). B.) Write an equation for the instantaneous **frequency** of the FM signal. C.).

The musical signal's form does never resemble a **square** **wave**. The **frequency** range perceived by an average adult hardly goes above 17KHz. Hence I do not give a dime to those heated discussions whether it's appropriate to test audio amplifiers using a 100KHz meander signal. But being an electronic engineer in my heart as well as by education and. . Let us see how the code for creating **square** **wave** looks like in MATLAB: Example #1 First, we will need an input time array to create our **square** **wave**. For that, we will define an input array with equally spaced values between -2 pi to 2 pi t = linspace (-2 * pi, 2 * pi) [creating an array of values between -2 pi to 2 pi] s = **square** (t).
