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 [...]

Today I have some ideas about how to get a signal. Which they are small circuits. You may be experiencing a problem with the sound. For example : The circuit has is not fixed gain.It has to be the automated control circuit. Or Learning about the audio signal is spread out, it’s very interesting. Or [...]

I had been using Dell GX620 Computer for a long time because it has good and durability. I lost it some days ago. My friend who is a computer repairer said the power supply is having problem. He told me to buy it at amazon.com,they are very nice it has low cost and free to [...]

You may had saw to a complicated AC light dimmer circuit ago. Now let’s look simple, but useful, fairly good. This circuit uses a capacitor in series with one lamp and accessories with a bit more. Is used to control the light dimmer, Easy and cheap. Power was reduced,without interference, the switch S2 is an [...]

This circuit changes the voltage to current, can provide dc current characteristics and AC so-so Circuit consists of 3 op-amps, 2 transistors is moderate. Passive devices and only a little. This circuit with grounded. load, it controls the rate Vout / Vin easily, it also has a wide area ranging from about 1 uA output [...]
