Audio Frequency Meter Circuit - Making Easy Circuits

The frequency meter circuit is the one about a Wien bridge which often when employed for frequency measurement provides the form displayed below:-. If Cx = Cs Rx = Rs, and Rb = 2 π. then f = 1 / 2 πCs Rs. or Rx = Rs = 0.628 f. where c. = C, = 0.1µf. Our calibration chart was worked out using this last formula.

Detectors are intended to be used for balancing bridge measurement circuits, potentiometric (null-balance) voltmeter circuits, and detect extremely low-amplitude AC (“alternating current”) signals in the audio frequency range. It is a valuable piece of test equipment, especially for the low-budget experimenter without an oscilloscope.

This sound frequency meter circuit is simple to build and can be constructed in a portable format. In can measure frequencies with a minimum level of 10 mVrms and a maximum frequency of up to 100kHz. It can be powered by penlight batteries since its standby current is 4 mA. The input is protected from high voltage levels up to 250 Vac.

Frequency Detection Circuit Design. Bookmark this question. Show activity on this post. I want to create a circuit that can detect audio frequencies and flash RGB LEDs different colors depending on the detected frequency. The frequency range will be from 20 Hz to 12 kHz, after looking at the chart below.

Simple Sound Detection Circuit. Detecting Sound

https://picaxe.com/docs/picaxe_sound.pdf

Simple Sound Detection Circuit. Detecting Sound Students often want to use ‘sound’ as an input within electronic projects. Unfortunately sound is not as easy to use as light and temperature, as there is not an instant ‘single component’ solution, as is the case with, for example, an LDR for light or a thermistor for temperature.
