... 2 Scalability: Capacitor Size Versus Frequency The chart shown in Figure 2 shows signal decay versus time normalized into time constants. (Note the semi-log scale.) After one time constant, only about 37% of the original signal remains. To achieve the goal of 10% maximum degradation, we need a time ...
