This program shows a signal generator, oscilloscope and loudspeaker. The signal generator can produce waves with various amplitudes and frequencies in the audio range. The oscilloscope shows the shape of these waves and has a scale with time-base control that allows you to measure the period and frequency of the waves.his program shows a signal generator, oscilloscope and loudspeaker.
