The … WebAug 16, 2024 · The frequency of a signal is the mutual of the time period ‘T’. So mathematically, it can be represented as f =1/T. So, the frequency can be calculated by using two steps like the following. First, need to find the periodic signal’s time period. From the above step, need to take the mutual of a time period for a periodic signal. Applications

WebCathode Ray Oscilloscope (CRO) is basically a graph displaying device. It draws a graph of an electric signal. It is an electronic test instrument, which is used to obtain waveforms when the differential input signals are given. The vertical axis (Y) represents Voltage and the horizontal axis (X) represents time. WebA PC-based oscilloscope is a type of digital oscilloscope which relies on a standard PC platform for waveform display and instrument control. In general, there are two types of PC-based oscilloscopes. Standalone oscilloscopes which contain an internal PC platform (PC mainboard) – common with upper mid-range and high-end oscilloscopes.
