Electronic Central Image Canceller Circuit Project
This is a Electronic Central Image Canceller Circuit diagram Project. The circuit allows you to eliminate the vocal portion of an audio signal, while leaving the instrumental portion. The circuit mixes two channels that must be 180° out of phase, so the signals that form the center-stereo image is canceled out. Electronic Central Image Canceller Circuit Diagram Those signals usually appear in phase. Resistor R3 biases the non inverting input of Ul from a center tap formed by resistors Rl and R4, and capacitor C3. Resistor R4, capacitor C3, and potentiometer R6 form a negative-feedback circuit that establishes the closed-loop voltage gain of Ul at unity. The signal is inverted between the input and output. Signals applied to the right input are coupled to the non inverting input of Ul through C4 and attenuating resistor R5. Resistors R3 and R5 make up a 6 dB attenuator, so once again, there is unity voltage gain between the input and the output. However, the right inpu...
