Circuit Diagram
Working Explanation
The audio signal conditioner circuit has a component called U1, which recognizes a tone and grounds the output at pin 8 for the duration of the input signal. If the audio wave is pulsed, U1’s output follows the input signal’s steps. The output of U1 goes to the base of a 2N3906 PNP transistor called Q1, which switches power on and off for a second 567 PLL called U2. As a result, LED1 flickers on and off in sync with the coded input signal. U2 functions as a set oscillator, producing a new output signal of a steady amplitude.
The tone that needs to be enhanced does not need to have the same frequency as the input signal, but it can be adjusted to a different frequency using resistor R8. R4, F8, and C4 determine the output frequency of the circuit. Transistor Q2 separates the output of U2 at pin 5 through external loading.
The circuit’s frequency-determining components’ real values allow the two PLLs to tune from a few hundred hertz to several thousand hertz. To increase or decrease the tuning range, one can increase or decrease the values of C2 and C4. Overall, the audio signal conditioner circuit enhances audio signals by creating a new steady-amplitude output signal with a frequency that we can adjust.
