Brown's book is good but even it does not have any question on Manchester encoder/decoder design, questions on Ethernet frame sequence detector and so on.Do u know of any book where I can find questions and explanations of the following type:
Example Question:
Design a Manchester Decoder. The Manchester Decoder should be oversampled
with a factor of two and convert the input sequence 01 to the output sequence 00.
The input sequence 10 should be converted to the output sequence 11. In case the
Decoder is out of phase with the incoming signal, it has to recover as fast as possible and take care of the sequences 11- and 00- in an appropriate way.
a) Deduce the Moore FSM for the Manchester Decoder and minimize it.
b) Write VHDL code for the Decoder. (NB! Don’t forget to take care of unused
states)
c) What would be a good state assignment for the FSM? (Hint! Some sequences will
be more probable than others - which ones?).
