Zusammenfassung:	DIGITAL MEMORY ADDRESSING SYSTEM A digital memory may be addressed with an analog signal utilizing a circuit comprising a digital to analog converter. A comparator compares the output of the digital to analog converter to the analog address signal. The output of the comparator is coupled to means for incrementing and decrementing a digital number in response to that output. The digital number incrementing and decrementing means has an output which is coupled to the addressing input of the digital memory. Switch means alternately connects the input of the digital to analog converter to either the output of the random access memory or the output of the means for changing the digital number.
