a demo showing how the jerkoff responds to different inputs. The X, Y & Z outputs are all shown responding to a variety of square wave, sawtooth and gate inputs. The input level, jerk and wiggle pots are all adjusted to demonstrate the different signals this circuit produces. The 'jerk' and 'wiggle' stages of each cycle are easy to recognise in the final section of the vid, when the 'scope is set to X-Y mode. The size of the jerk is controlled by the jerk pot and the degree of wiggle is controlled by ......
