4047/4066 audio slicer
You need to connect pins 1 and 13 of the 4053 to the virtual ground rail (top of C4), not the circuit's 0V rail.
The CD4053 is a triple 2-channel analog multiplexer/demultiplexer integrated circuit, widely used for routing analog signals...
Audio Noise Filter Circuit
This audio noise filter circuit is a bandpass filter designed for the audio frequency range. It effectively filters out unwanted signals that fall below or above the audio frequency spectrum.
The audio noise filter circuit operates as a bandpass filter, which...
Audio Filters Circuits Projects
This audio noise filter circuit is a bandpass filter designed for the audio frequency range. It effectively filters out unwanted signals that fall outside the audio frequencies. The circuit consists of two filters: a low-pass filter and a high-pass filter...
LM1894 Principles and Applications a
A typical representative of dynamic noise reduction developed by the United States National Semiconductor is the LM1894. Its principle is illustrated in Figure 1-1070, where the left and right input signals are processed through a main signal path. The input...
Central-image-canceller
The circuit is designed to eliminate the vocal portion of an audio signal while preserving the instrumental portion. It achieves this by mixing two channels that are 180° out of phase, allowing the signals that create the center-stereo image to...
Audio Beat Detect ?« Electronic Product Design
This circuit employs a digital potentiometer to enable the microcontroller to automatically adjust the circuit's gain according to the ambient audio volume. However, a standard potentiometer can be used if automatic adjustment is unnecessary. The low-pass filter design is based...
Audio Electronics
This document outlines the use of a desktop computer to perform complex arithmetic for designing state-variable filters intended for audio applications. It features the construction of a tunable notch filter for measuring harmonic distortion. The article has been well edited...
Second-Order Audio Filter Performs Multiple Functions
The second-order multipurpose filter described here can function as a low-pass, bandpass, high-pass, or notch filter at audio frequencies. Its unique feature is the ability to independently vary all characteristics using potentiometers. In basic filters, only one k value is...
electronic circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, immediately discontinue electrical flow....
