In this project we are building a basic and low cost frequency counter circuit . It can measure from 16Hz to 100Hz signals with a maximum amplitude of 15V. The sensitivity is high, the resolution is 0 ...
The circuit has been designed for a person who loves to jog or walk while measuring the distance that have been covered during the activity. 4093 – a quad 2-input NAND with Schmitt trigger inputs ...
In frequency counters, the gating time allotted for counting is often too short to resolve low frequencies. A phase-locked loop could be used to multiply the input frequency. But in some cases, the ...
