A digital frequency meter is a digital circuit that measures the frequency of a periodically varying signal. It is an indispensable measuring instrument for scientific research and production fields such as computers, communication equipment, audio and video. It is a digital measuring instrument that displays the frequency of the signal being measured in decimal numbers. Its basic function is to measure sinusoidal signals, square wave signals and other physical quantities that vary in unit time. In the process of designing, installing and debugging analog and digital circuits, the digital frequency meter is often used because of its use of decimal number display, rapid measurement, high precision and intuitive display.
