It also includes utilities that allow for the rapid simulation of complex waveforms like polygon, band, or frequency response. This provides the capability of digital signal capture from an analog input, which is used to perform a variety of tasks ranging from simple tests of voltage and capacitance across different loads, to complex modeling and synthesis of complex physical processes. ORCAD PSpice Designer and Capture are a high-end CAD/CAM software application, which allows for complex process modeling and simulation of electrical signals.
