此为简易的频率计,可测10hz到1Mhz的频率,通过整形电路测方波,三角波,正弦波,还具有自校功能,也可测周期,这个为自己做的仪器原理的课程设计,里面包含程序及设计报告。可方便大家的使用。测量误差《0.1
This is a simple frequency counter can measure the frequency of 10hz to 1Mhz, measured by square-wave shaping circuit, triangle wave, sine wave, also has self-calibration function can also test cycle, the equipment to do this for their own principles of curriculum design, which report contains the procedures and design. We can easily use. Measurement error, " 0.1 (2010-07-14, Asm, 119KB, 下载75次)
