      Change the quadrature demod filter to sync block · c1677c81
      Manolis Surligas authored
      Seems that there is a probleb with general blocks and the history, so
      the filter cannot act as valve. However, it produces zeros, in the
      presence of noise.

      Add a quadrature demod filter · 0d5b2959
      Manolis Surligas authored
      This is an attempt to cut the signal free period after the quadrature
      demodulation block. The idea seems that works, but there still an issue
      with the samples not passing correctly from the valve.

      Morse tree traversal is working · d307d6ac
      Manolis Surligas authored
      Depending the received symbol the tree is traversed towards the leafs.
      At each step the corresponding decode-able character is appended at a
      string buffer. 
      * Add logic in the decoder to retrieve the decoded words from the tree
      * Create a debug source block

      Add morse decoder block. · ca49f817
      Manolis Surligas authored
      The morse decoder is not yet functional. The decoding is performed
      using a binary tree. Left child, corresponds to a received dot whereas
      right to a received dash.
