April 8, 2019 hwmadeeasy Design a high-pass Butterworth filter with a lower half-power frequency of 1 kHz by modifying the circuit of Figure 6.12(a).

April 8, 2019 hwmadeeasy 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.
