1. What is ASCII (8-bit binary) representation of letter z?
   1. Display digital representation of ASCII letter z using signal level zero for binary 0 and signal level 1 for binary 1.
   2. What is the fundamental frequency of signal representing letter z assuming signal is periodic with period T = 8?
   3. From the Fourier series expansion of the signal representing letter z, compute the following:
      1. Constant component c of signal
      2. Amplitudes a_n and b_n for the first 10 harmonics i.e. n = 1 to 10
   4. Compute the root mean square value (RMS) for the first 10 harmonics.
