Signal Processing Graphically

Slide 1

Signal Processing 4.0 provides an easy to use graphical user interface (GUI) that can be used for manipulating signal data and performing complicated calculations. In this example, we will create a signal with 5, 15 and 30Hz components, and then use the Signal Processing tool (sptool) to design a digital filter to retain the 15Hz signal. Above are the commands to produce the signal and launch sptool.
