Chapter 1 Linear Wave Shaping
1.1 INTRODUCTION
Let us consider a transmission network consisting of linear elements. Sinusoidal signal is applied to a network, the output signal is sinusoidal in the steady state conditions. The influence of the network circuit on the signal may be completely specified by the ratio of output to input amplitude and phase angle between output and input waveform. No other periodic waveform preserves its shape. Generally when transmitted through a linear network the output signal may have a little resemblance to the input signal.
“The process whereby the shapes of non sinusoidal signals are shaped by passing the signal through the linear network is called linear wave shaping”.
