Edgar Allan Poe, Charles Baudelaire, pseudo-random sequence generator is shown in figure 7-1. This figure shows by way of example an 8-bit shift register containing bits . to . inclusive, which is connected via a set of switches . to . inclusive with the mod 2 adding network. The output of this network is the input of the shift register.

Binary Counters,with zero. Binary counting is simple since the concepts of numerical weight and binary weight agree for that code. Counting is an accumulative process. A 4-bit binary code was shown in column 2 of table 1-1.

Reflected Binary Counters,r example in mechanical analog-to-digital converters where the position of a shaft has to be translated into a digital word. When using code discs with the natural binary code for this purpose, ambiguities in the sensing of the code strips on the disc (mechanical or photographic) by means of a readi

Pseudo-random Sequence Generators, the next state of the counter is determined from the present state by means of a mod 2 adding network connected with the outputs of a number of shift register sections. This adder determines the least significant bit of the next state which is shifted into that register while the present state word

These mathematical functions can for instance be the square or a higher power of ., the square root, the log., the sin or the cos of ..[l] The next value of the function must be available immediately after the next counting pulse is received.
