Noise limiter signal

Interference from ignition noise pulse of the engine, it can cause various problems associated with radio communication equipment installed in the car.This circuit improves signal to noise ratio (S / N-ratio) was better, To connected between the output of the detector circuit with the audio input (if high impedance) or region of the impedance between the high dance audio section.
The diode D1 and diode D2 is there any way to direct the resistance is quite low and very high back resistance.
This circuit for the rf receiver have low bandwidth still 2kHz also 3 kHz

Low pass filter circuit 10KHz using uA741

This be the circuit filters 10KHz low size frequencies s use IC op-amp the highly popular number uA741. By this circuit convenients for to apply to input and output of the circuit changes analog signal be digital or the circuit changes digital signal be digital. In sound system of digital for synthetic the voice or music give for make wave form output the smooth. And press the noise that happen at output. When small-sized signal was managed with decrypt linear the size is 8 bit. Read more

Low noise tone control circuit using C945

If you have electronics old equipment, keep many long ago year, unknow build Electronic Project good. I begs for to advise pre tone control circuit this. By it can fine to decorate the sound Bass,Treble and Volume well.There is the prominent point that use transistor, But be of good quality of good sound doesn’t be defeated the circuit that uses the integrated circuit. By the thing that me observes clear, be the noise is low, bland sound are good. from your circuit can use transistor number C945 or C828 or C1815 can replace. Which the price is inexpensive the hardware is other may get not difficult. The power supply , should choose that be model dc regulator 12V to 24V building may use PCB a bird purposes all right which , good easy.
