Step of 4 17.012E Refer to Figure 16. 14 in the textbook for first order all pass filter. Draw the circuit in s-domain representation. R₁ R₁ V V⁺ + + R 1 sC Figure 1 Step of 4 Apply voltage division rule to calculate the voltage at the non-inverting terminal. As per virtual ground concept, the voltage at the inverting terminal is equal to the voltage at the non- inverting terminal. = Step of 4 Apply nodal analysis at the inverting terminal. Substitute sRC Replace for Step of 4 Calculate the phase shift from the transfer function. The phase of the all pass filter is 90° at = rad/s (RC is always positive value) Assume the value of the resistors, for one possible value of capacitor. Thus, the values of the resistors are and the value of the capacitor is
