huffmam_decoding
the decoding of Huffman codes is shown. For the decoding the coding tree has to be constructed using the information which has to be transmitted as well.
Following that the input is read bitwise and for each 0 a left turn is taken and for each one a right turn until a leave is reached. In this case the value of the leave (usually a character) is output, continuing after that at the root.

Fifth problem, Pattern Simulation of inverse transform
Ⅰ, basic tasks: decision by the sampling pattern after AMI and CMI pattern sequence to recover the original digital PCM pulse code signal.
Main steps and requirements:
(1) post-judgment by the AMI code sample digital sequence to restore the original PCM pulse code signal (signal 0,1). AMI requires post-judgment sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
(2) post-judgment by the CMI sampling digital code sequence to restore the original PCM pulse code signal. Requirements of post-judgment CMI sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
Ⅱ, choose to do the task: the post-judgment by the sample type HDB3 code sequence to recover the original digital PCM pulse code signal.
