Digital sound and light control stairs delay switching circuit
The CDI011 integrated circuit is designed for a sound and light-controlled stair delay switch circuit, which is relatively simple and effective. It utilizes a combination of NAND gates and differential input dynamics. The circuit has two input terminals; when the...
Mini-stereo
This circuit is constructed using two integrated circuits: the MC1458 dual operational amplifier, configured as a preamplifier, and the LM378 dual 4-watt amplifier. The gain of the preamplifier is determined by the resistor ratios R3/R1 for one channel and R4/R2...
BA3822 five-point stereo graphic equalizer circuit design
The BA3822 is a five-point stereo graphic equalizer integrated circuit that operates with two channels. Each channel can independently set five center frequencies using external capacitors. This integrated circuit supports a wide operating power supply voltage range (VCC = 3.5V...
Stereo Noise Limiter Circuit
This stereo noise blanker or suppressor attenuates noise by 45 dB when the music signal is low or absent; it functions primarily as a noise limiter. The noise blanker sensitivity...
This circuit serves as a stereo noise blanker or suppressor, designed...
Build a Variable-Frequency Audio Band pass FilterCircuit
This variable-frequency audio bandpass filter is constructed using two 741 operational amplifiers connected in cascade. The two 741 op amps are configured as identical RC active filters and are cascaded to enhance selectivity. The filter's tuning range spans from 500...
Stereo Audio Isolator
This circuit is useful for removing ground loop hum on a remote line level audio signal line. It can be used to connect a computer sound card to a stereo amplifier's line input. Other uses include tapping into a line...
Octave Equalizer Circuit
This circuit represents a section of an octave equalizer utilized in audio systems. The table outlines the values of C1 and C2 required to achieve specific center frequencies. This circuit can provide a boost or cut of 12 dB, which...
1W stereo Headphone Amp (TDA2822)
A stereo power amp designed for use in portable players and radios. A 3V supply can be used to drive headphones providing 20mW in 32 Ohms per channel. A 9V supply will provide 1W in 8 Ohm per channel for...
10 band equalizer
The equalizer described is designed for hi-fi installations, public address systems, mixers, and electronic musical instruments. Relay contacts at the inputs and outputs, in conjunction with switch S2, allow for the selection of the desired channel. The input can be...
