In the following figure, the transmitter T_x sends a wideband modulated RF signal via a coaxial cable to the receiver R_x. The output impedance Z_T of T_x the characteristic impedance Z₀ of the cable and the input impedance Z_R or R_x are all real.
Which one of the following statements is True about the distortion of the received signal due to impedance mismatch?

A) The signal gets distorted if Z_R ≠ Z₀, irrespective of the value of Z_T B) The signal gets distorted if Z_T ≠ Z₀, irrespective of the value of Z_R C) Signal distortion implies impedance mismatch at both ends Z_T ≠ Z₀ and Z_R ≠ Z₀ D) Impedance mismatches don't result in signal distortion but reduce power transfer efficiency
