Sketch a waveform that shows an Intended transmission in the
physical layer and what that waveform could look like if some of
the factors that can cause errors are introduced. Device an
encoding scheme that is capable of encoding eight, three-bit
transmissions using both Amplitude and frequency modulation for
each of the eight encodings. Sketch a second waveform for the
transmission of 010, 011,110 and 111, as encoded by you in the
previous part of the problem.
