Explanation: When signals are transmitted in transmission lines like telephone wire, they undergo change in phase, all-pass filters are used to compensate these phase changes. 9. Determine the output voltage for all the all-pass filter and express it in complex form?
A. VO =Vin/ [(1-j2πfRC) /(1+ j2πfRC)]
B. VO =Vin× [(1+j2πfRC) /(1- j2πfRC)]
C. VO =Vin ×[(1- j2πfRC. /(1+ j2πfRC)]
D. None of the mentioned
