发明名称 Multi channel digital random access recorder-player
摘要 A multi-channel digital random access recorder-player receives an analog audio signal, converts the audio signal into a digital signal, and stores the digital signal in a memory for random access. The memory includes sixteen channels, each channel having sixteen memory boards, each channel and each memory board being assigned a unique four bit binary address by an address counter. An external control is provided by which the user selects an address for recording or playback and a comparator compares the selected address with the addresses of the memory. When the memory address corresponding to the selected address is detected, that memory board is enabled so that data can be recorded on the memory board or retrieved from the memory board for playback through an audio output device such as a loudspeaker. The recorder-player thereby provides random access to a memory. Also provided is a system in which several modules, each with a logic board and a memory, are combined into a single system.
