Abstract

This paper describes and analyses a method for coding signals based on digital filter structures with two´s complement overflow characteristic. First the basic principle is introduced. Second the encoder-decoder-system is compared with classical (simple) cryptographic systems and analysed using methods known from cryptoanalysis. Then encoding and decoding of ASCII text and bitmap pictures as well as speech and music are shown as application examples. The influence of transmission errors on the decoded signals is discussed
