4.25 The binary data stream 011100101 is applied to the input of a modified duobinary system- (a) Construct the modified duobinary coder output and corresponding receiver outputy without a precoder. (b) Suppose that due to etror during transmission, the level produced by the third digit is reduced to zero. Construct the new receiver output. 4.26 Repeat Problem 4.25 assuming the use of a precoder in the transmitter.
