  2. Measurement Texas Instruments CD4070B CD4093B CD40106B LM339A LMV324
    David Conrad Electronic Design The challenge in measuring low frequencies is that the counter gate time is often too short for the signal relatively long period. This non-critical circuit automatically multiplies an input single frequency times ...
