👉 An oscillometer is a type of instrument used for measuring the frequency and amplitude (or phase) of a periodic signal. It consists of an oscillator, which generates a periodic waveform, and a display device that displays this waveform on a screen or monitor. The key features of an oscillometer include: - A period: The time between two adjacent oscillations. - Frequency: The number of cycles per unit time (or frequency). - Amplitude: The maximum value reached by the signal over its entire
