Description: 1. VHDL design and simulation completed 12 decimal digits frequency meter. 2. Frequency measuring range: 1Hz~10KHz, divided into two bands, namely 1~999Hz, 1KHz~10KHz, with three digital display of measured frequency, with LED display showing the unit, such as a green light indicates Hz, red indicates KHz . 3. With automatic calibration and measurement two functions that use standard clock calibration, measurement accuracy. 4. With over-range alarm function when beyond the current range for the measuring range, emit light and sound signals.
