3) Evaluate the digital modulated signal given below and develop the output equation for the modulation scheme for the 4th discr levels are 8 , and the frequency of the modulated 4) Differentiate between the coherent and Non-Coherent detection and hence write the orthogonality condition for each. (10 marks) 5) With the help of the concept on error controlling using a hamming code, and if the data is 1111100 develop the composite data at the transmitter, with all the necessary steps
