Integrable bidirectional shift register in analog-to-digital converter

摘要

A multistage bidirectional shift register for a differential pulse code system, simple enough to be integrated inexpensively, is achieved by taking advantage of the code configuration conditions permitted by the pulse code system. The system requires only a single stage of the register to be switched at a time. This enables odd and even stages of the register to be switched independently and leads to the employment of relatively few elements per stage.
