1 Hz to 1 MHz Frequency Reference Generator Circuit Diagram
This circuit is an universal frequency generator which you can use in numerous frequency and time period testing applications. It is primarily well suited for a gate pulse generator in frequency counters. The circuit is capable of generating an entire range of reference frequencies such as 1 Hz, 5 Hz, 10 Hz, 50 Hz, 100 […]
Simple Frequency Meter Circuits – Analogue Designs
The following simple analogue frequency meter circuits can be used for measuring frequencies which may be either sine wave or square wave. The input frequency which is to be measured must be at least 25 mV RMS, for optimal detection and measurement. The design facilitates a relatively wide range of frequency measurement, right from 10 […]
Extremely Low Frequency (ELF) Radiation Monitor Circuit
ELF stands for Extremely Low Frequency, which is an electromagnetic radiation generated by most of out household electrical equipment. Regarding the effect and severity of ELF fields on human health, debate remains heated. However, I believe there is enough data for us enthusiasts to adopt a conservative stance on the level of exposure we must […]
3 Simple Frequency Counter Circuits Discussed
In this post we are going learn how to construct 3 different frequency counter circuits using ordinary components and ICs which will showcase the measured frequency on 7 segment displays. The first circuit which uses 4026 ICs can measure frequencies up to 1 MHz and the circuit is user calibrated. We will Learn About: Block […]
5 Digit Frequency Counter Circuit
This digital frequency counter will provide a direct reading of the frequency applied at its input, through a 5 digit common cathode display module. The compact frequency counter can be used for accurately counting the frequency or pulse from any intended source. Main Applications It can be also used for measuring the RPM of a […]
