a) The bipolar signal scheme is often used in practical Pulse Code Modulation (PCM)systems due to it possesses one-bit error detection ability. Assume that the binarysource symbols zeros and ones occur equally likely, and let the transmitting filtershaping has an impulse response,D=9hr(t) = AxrectA=51. What are the factors which control the Power Spectral Density (PSD) of thebipolar signaling scheme?2. Construct the Non-Return to Zero (NRZ) bipolar format for the binarysequence10010101011 (be careful to use h7(t) to draw the sequence)3. Determine the PSD of the NRZ bipolar signaling scheme.
