You are given an input signal x(t), which is plotted in Figure P6.13. You are given two different filters: One is a low-pass filter and one is a high-pass filter. The input signal x(t) is filtered with each of these two filters, and the two outputs are also plotted in Figure P6.13. (a) Is Filter A a low-pass or high-pass filter? Explain your answer. (b) Is Filter B a low-pass or high-pass filter? Explain your answer.
