... (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 constant of 0.1 from the chart. From Figure 1 again, we see we need to assure this degradation occurs within a half-cycle of frequency f, ...
