Step 1 of 4 17.024E Refer to Figure 16.26 in the text book. The center frequency of the KHN biquad filter is, R Substitute rad/s for , 10 nF for in equation. = 10 kΩ Step 2 of 4 Consider the equation. Rd = QR Substitute 5 for 10 kΩ for R in equation. Rd = 5x10 = 50 kΩ The capacitance C₁ is C₁ = flat gain Substitute 1 for flat gain in equation. = 10x1 nF = 10 nF Step 3 of 4 The resistance is, R Substitute 1 for gain, 10 kΩ for R in equation. = 10 kΩ Step 4 of 4 The resistance is given by = gain Substitute 5 for 10 kΩ for r and 1 for gain. = 50 kΩ Therefore, the design parameters is 10 nF Rd is , R is , is is 10 kΩ and is 50 kΩ
