Audio Frequency Signal Generator Schematic
https://www.theprojectasylum.com/electronicsprojects/signalgenerator/signalgeneratorschematic.html
In the upper left of the schematic is the frequency generator section. The bottom left is the power supply and the right half of the schematic is the counter / display section of the unit. The JU1 jumper in the schematic is the access point for external use of the internal counter. To externally use the internal counter the jumper needs to be removed and the external signal (maximum …

Audio Oscillator with Frequency Counter. This project is not completely new. In fact, the oscillator is made from the same schematic as in one of my previous projects and only the frequency counter is made with different schematic. After I finished the oscillator, I made some minor changes in the square signal part of the schematic.

43631. A frequency counter measures the frequency of an input signal. These are commonly used in laboratories, factories and field environments to provide direct frequency measurements of various devices. Most frequency counters work by using a counter that accumulates the number of events (oscillations) occurring with in a specific period of time …

Inputting a constant frequency into a counter results in the division of the frequency. A one-bit counter will divide the input frequency by 2. A 4 bit counter can divide the input frequency by 16. A BCD counter divides the input frequency by 10. 74151 Multiplexer These are used to select between up to 8 input lines. A thee bit address is fed to the multiplexer, which selects the …
Analogue audio frequency counter - Page 1

Hi I have found this frequency counter circuit which worked ok but I have a problem. The range I am interested is 480Hz-2.7KHz only. Can I transform the circuit somehow to cover only this range, so that the meter spreads throughout it's whole scale instead of part of it, so as to increase the resolution of the meter?
