CHAPTER 6 FILTERS214ANSWERIt decreases.If you had diﬃculty with these ﬁrst three problems, you should review the examples in Chapter 5.CAPACITORS AND RESISTORS IN SERIES4 For simplicity, consider all inputs at this time to be pure sine waves. The circuit shown in Figure 6.2 shows a sine wave as the input signal to a capacitor.VinVoutCGroundFIGURE 6.2QUESTIONIf the input is a pure sine wave, what is the output? ANSWERA pure sine wave5 The output sine wave has the same frequency as the input sine wave. A capacitor cannot change the frequency of the signal. But remember, with an AC input, the capacitor behaves in a manner similar to a resistor in that the capacitor does have some level of opposition to the Book Authorc06V107/04/2012 3:08 PM c06.indd 2147/4/2012 3:08:45 PM
