Audio frequency counter using AT89C52 micro controller March 30, 2015 By Ashutosh Bhatt Audio frequencies mean the range of frequencies that a normal human can hear through his ears. It is from 20 Hz to 20 KHz. But in general, practically most of the sounds we hear around us are in the frequency range of 100 Hz to 2000 Hz.

The IF frequency can be loaded by using the dip switches on the counter board (BCD value). The counter chip used is 74HCT190. This IC consumes less power and counts up to say 50MHz. If you are not in a position to get HCT version you can replace the same with any family of 74 series. the decoder IC is CD4511.

Figure 1 exhibits the circuit diagram of the 10-MHz digital Frequency Counter. The circuit includes an ICM7208 seven-decade counter (U1), an ICM7207A oscillator controller (U2), and a CA3130 biFET op amp (U3). IC U1 is used for counting the input signals, and then decode them to 7-segment structure. It additionally is used for generating the output signals for driving …

It’s a type of AC track circuit in which audio frequency signals are used instead of pure AC or DC signals. Its generally a joint less track circuit, extremity of the tracks are defined by tuned units but can also be used with IRJs. it is least prune to interference and hence can be used in ac, dc, and non electrified areas.
