- Page 24 The second is non-linear distortion and refers to a change in waveshape produced by application of the waveshape to non-linear elements such as vacuum tubes, an iron core transformer or a clipper network. The third is delay or phase distortion, which is distor- tion produced by a shift in phase between some com- ponents of a complex waveform.
- Page 25 Fig. 3 0 shows a graphical development of a similarly tilted square wave. The tilt is seen to be caused by the strong influence of the phase-shifted 3rd harmonic. It also becomes evident thar very slight shifts in phase are quickly shown up by tilt in the square wave.
- Page 26 Fig. 3 4 indicates high-frequency boost in an amplifier accompanied by a lightly damped "shock" transient. In this case, the sudden transition in the square wave potential from a sharply rising, relatively high frequency voltage, to a level value of low frequency voltage, supplies the energy for oscillation in the resonant network.
