Numeric edit fields — allow users to enter the pulse frequency and length. MATLAB® automatically checks to make sure the values are numeric and within the range specified by the app.

Switches — allow users to control automatic plot updates and toggle between plots in the time and frequency domains.

Drop-down menu — allows users to select from a list of pulse shapes, such as Gaussian, sinc, and square.

Knobs — allow users to modify the pulse by specifying a window function, modulating the signal, or applying other enhancements.
