Title: Long life telephone answering machine - has solid state memory with converters for changing between analog and digital operating modes
Inventor: KRAPP KARL-HERMANN ING GRAD
IPC: H04M1/65
Filed: 1978-12-16
Abstract: The design eliminates the cassette and replay head required in conventional answering machines. It employs a solid state memory in which the message for response to a call is stored, and from which it is replayed when a call is received. To record and replay the message analog to digital, or digital or analog converters are provided at the memory input and output. These converter units typically employ a delta-modulator and a binary converter. The delta-modulator produces digital signals of varying length from the analog signal or vice versa. The solid state memory can be a charge coupled device or a magnetic bubble store. As the proposed equipment does not record incoming messages there are no moving parts. Wear is thus eliminated and maintenance greatly reduced.
