Design features: 1. . Complete with VHDL 12-bit decimal digital frequency meter design and simulation. 2. Frequency Range: 1Hz ~ 10KHz, divided into two bands, namely, 1 ~ 999Hz, 1KHz ~ 10KHz, with three digital display measuring frequency, with LED display that unit, such as the green light that Hz, red light, said KHz. 3. Calibration and measurement with automatic two functions, namely, the clock can use the standard calibration, measurement accuracy. 4. Super-range alarm function, beyond the scope of the present range of measurement files, the issue of light and sound signals.
