Demonstrates the use of the Control Clipper block for limiting the frequency range of an oscillator.
The Exponential Frequency Controller generates a frequency control signal sweeping from a low value (preset to
100 Hz) to a high value (preset to 22050 Hz). The Control Clipper then limits the frequencies to within the selected
range (preset to lower value of 300 Hz, upper value of 700 Hz). By varying the parameters of the Control Clipper, the
envelope of the frequency sweep can thus be changed. Note that the Control Clipper can be used to clip any type
of control signal (e.g. for amplitude signals as well as for frequency signals as illustrated here).
(To compare with the result without the Control Clipper, temporarily bypass the Control Clipper by connecting
directly from the Exponential Frequency Controller to the Controllable SineWave Oscillator.)
