Hearing Frequency and AmplitudeThe best way to understand frequency and amplitude is to hear the effect of changing them. We will control a sine wave oscillator, which produces a very smooth tone.
The output of the oscillator will be sent to an on-screen oscilloscope so that we can see the effects visually. The waveform display has time on the horizontal axis and the value of the oscillator output on the vertical axis. It is updated automatically about once per second.
