The digital filter output data is converted to a current-mode analog waveform by a digital-to-analog converter. |
In order to simultaneously output and input a waveform, the sound card must be capable of full duplex operation. |
If the magnet is in the middle of the vibrating string, the waveform should be a symmetrical square wave. |
This circuit does not have the monostable multivibrator macro between the switch bounce waveform and the counter. |
This is so because the waveform exhibits interference effects, meaning that ALL these states exist in potentia. |
The CODEC then converts the digital FM audio signal into an analog waveform for conversion to sound. |
