Digital frequency meter is a decimal digital display of the measured signal frequency digital measuring instruments, its basic function is to measure sinusoidal signals, square wave signal, a sharp pulse signal and various other units within the time-varying quantities. Digital frequency meter with digital display instrument measured signal frequency, the signal may be a sine wave, square wave or other periodic changing signals. As with appropriate sensors, it can be a variety of physical tests, such as mechanical vibration frequency, speed, sound frequency and product piecework like. Therefore, the digital frequency meter is very broad application.
The high-speed comparator and complete measurement module FPGA design, and ultimately related functions on STM32 microcontroller, and the index has reached the predetermined requirements.
