1. Consider transmission of binary data using the following pulse amplitude modulation scheme: binary sequence 00 is encoded as symbol o binary sequence 01 is encoded as symbol 1 . binary sequence 10 is encoded as symbol 2 . binary sequence 11 is encoded as symbol 3 Note that this is a form of linear modulation. Assume the communication system operates with a bit rate of 1000 bits per second. Assume the pulse shape p(t) is rectangular with value 1 over the entire symbol interval. (a) Give a signal constellation for the modulation scheme. Label each symbol value with its corre sponding bit sequence. (b) Sketch ult) for the binary sequence 00 10 11 01. That is, plot the baseband I and Q waveforms. (c) Sketch the corresponding passband communication signal p(l) assuming a carrier frequency of 200kHz. 1.
