Sinusoidal Steady State 6.002 Fall 2000 Lecture 16 1 .Review We now understand the why of: 5V R L C v Today, look at response of networks to sinusoidal drive. Sinusoids important because signals can be represented as a sum of sinusoids. Response to sinusoids of various frequencies -- aka frequency response -- tells us a lot about the system 6.002 Fall 2000 Lecture 16 2 .Motivation For motivation, consider our old friend, the amplifier: V S Demo vO R vi VBIAS + – + – CGS vC Observe vo amplitude as the frequency of the input vi changes. Notice it decreases with frequency. Also observe vo shift as frequency changes (phase). Need to study behavior of networks for sinusoidal...
