Description

The wave generator is fed simultaneously into the audio amplifier/loudspeaker and the oscilloscope, to prevent loading of the generator by the speaker and the concomitant distortion. The sound and wave shape can then be simultaneou sly observed for sine waves, square waves, sawtooth waves, and a number of other wave shapes. The effect of changes in the frequency as well as the wave shape can also be observed.
