Waveforms

The amplitude of a waveform is the value of the voltage or current, and it varies in value during one cycle of a wave. The peak-to-peak (p-p) amplitude of a wave is easily measured on the face of a CRO tube (Figure 6.1), where it is found by measuring the vertical distance in centimetres between peaks of the wave and then multiplying this distance by the settings of the Volts/cm switch of the oscilloscope.
