The BIP Sine Wave Generator uses the sound card's output as sine wave output. A built in sweep algorithm is used by audio hackers to measure frequency repsonses of their amplifiers.The generator has the following properties:

Sampling frequency:
The oscillator automatically uses the highest sample frequency available at the output that you select (usually maximal 44 kHz but people with 22 kHz max. also use the generator without any problems).

Ounput impedance:
The same as the output impedance of your sound card. Normally the output of a sound card is very low (which is good) in order to be able to connect a speaker (which is not needed for this application).

Accuracy:

The generator uses 8-bit samples to generate the sine wave signal. The sine wave is created using a secret algorithm which makes use of special floating point instructions of your microprocessor.
