Abstract: Extensive research is carried out in signal coding to achieve wideband speech signals and in this area we took the modified block truncation coding for study. The modified image coding is done to change the original BTC algorithm for processing black and white images where we preserve the basic principles. We found that the modified algorithm addresses the speech signal and images where the signal quantization is implemented. The experimentation revealed that the algorithm is effective and lead to the wider implementation of the algorithm for speech signals.
