Audio Equalizer Circuits
This discussion continues from the audio tone control topic, which introduced both passive and active tone controls. The follow-up topics may include a 2-Band Active Tone Control or a 3-Band Active Tone Control. An audio equalizer is utilized to adjust...
ROTARY SWITCH DEBOUNCE
A three-stage active Butterworth bandpass input filter is utilized in a radioteletype demodulator to differentiate RTTY tones from one another and from noise. The filter is centered at 2200 Hz and has a bandwidth of approximately 260 Hz, allowing for...
Double five-band equalizer circuit
Figure 1-98 illustrates a double five-band equalizer circuit featuring a secondary connection. In this configuration, IC1 and IC14 serve as voltage amplifiers for each channel of the equalizer. The circuit also includes IC11, IC24, IC2, IC34, IC31, IC12, IC23, IC22,...
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...
RC Low-Pass passive Filter
What is the purpose of this circuit? Basically it has two roles: to pass the desired low frequency signals and stop the unwanted high frequency signals. Open the netlist file lpfilter1.cir with your SPICE simulator. Most simulators display the netlist...
Arduino Vocal Effects Box
This Arduino-powered vocal effects box pitch shifts and distorts incoming audio signals to produce a wide variety of vocal effects. This project is an experiment with real-time digital signal processing using Arduino. It samples an incoming microphone signal at a...
SYNCHRONOUS FILTER FOR ADF
Separates 130-cps motor drive voltage from voice frequencies in the output of an ADF receiver. P. V. Sparks, Servo Filter and Gain Control Improve Automatic Direction Finder, Electronics, 34:23, p 110-113.
The circuit described functions as a filter that effectively separates...
5-Band Graphic Equalizer with LA3600
This complete high quality, low noise 5-BAND GRAPHIC EQUALIZER circuit is based around Monolithic Linear integrated circuit LA3600 manufactured by SANYO. This circuit is very easy to build and has good Quality. You can use it with Portable component stereos,...
5 Band Graphic Equalizer
Cleaned Input: Another unit of graphic EQ with five bands. The basic difference with the other circuits is that instead of an IC, a transistor is used and the power supply goes up to +/- 24V DC, ensuring low distortion...
