As the output voltage of the rectifier exceeds the decaying voltage of the capacitor, impulse noise is produced in the charging circuit which can get transferred into the audio circuit if they share the same piece of copper in either of the power lines.
PC Speaker Amplifier : 6 Steps (with Pictures) - …

It use TIP31/32 transistors as push-pull output stage.. I’m using common LM7812 voltage regulator circuit and 220V(in)/15V(out) wall adaptor as power supply because the amplifier circuit requires less than 1A current during normal operation. It’s quite satisfying as output level is adequate enough to drive any of 8ohm or 4ohm speakers I have.

Basically, I wanted to build a circuit to amplify the audio output coming out of my PC's headphone jack to make it as loud as if it was coming out of a speaker. It seems that the best way to do this is to either use an IC in the circuit, or just buy some speakers. It would be neat if there was a program that could amplify sounds being played on ...

1. Use a - stereo to mono - audio adapter, so you get both channels of FLdigi audio output going into the audio derived cw keying circuit.( NOTE: this is NOT for FLdigi in AFCW mode ) 2. Use an - 8 ohm - to - 200 ohm - audio transformer - for better power transfer between your sound card output and the circuits input.

Say your speaker system can output up to 20V, then you need a 20:1 divider. To allow for a lowish mic in input impedance the divider output impedance should ideally be 1kΩ or less. So in this case ideally you would use 19kΩ for the top half (20kΩ will do, you don't need to be too exact) and a 1kΩ pot for the bottom half (R2).

To calculate the voltage that this will output from the DAC, we use the following equation: voltage output from DAC = [ (value sent to PORTD) / 255 ] * 5V so for PORTD = 125: voltage output from DAC = ( 125 / 255 ) * 5V = 2.45V The code below sends out several voltages between 0 and 5V and holds each for a short time to demonstrate the concepts I've described above.
