These can be fed back to the oscillocope in order to generate Lissajous figures in the x-y mode. The signals are available at the speaker output of the sound card. The signal can be defined by a mathematical formula as well. The oscilloscope contains in addition a signal generator for 2 channels for sine, square, triangular, sawtooth wave forms and different noise spectra in the frequency range from 0 to 20kHz. Be aware, that most microphone inputs are only mono. The low frequency end is limited by the AC coupling of the line-in signal. The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution.
