METHOD FOR RECORDING A SINGLE OR DUAL SIGNAL AND A MULTI-LEVEL ANALOG SIGNAL AND REPRODUCING SYSTEM INCLUDING AN INDEPENDENT CONTROL TYPE SIGNAL STORAGE SEGMENT HAVING PERMANENCY WHICH CAN SELECT IN AN EXTERNAL

摘要

PURPOSE: A method for recording a single or dual message and a multi-level analog signal and reproducing system including an independent control type signal storage segment having permanency which can select in an external is provided, which records and reproduces a single or dual message and a multi-level analog signal. CONSTITUTION: The reproducing system comprises: a recording circuit (155-170) for receiving an audio signal and generating a filtered signal; an analog storage array (150) to be connected to the recording circuit (155-170) for storing the filtered signal; a control circuit (180) to be connected to the analog storage array (150) for controlling a duration of the filtered signal; and a reproduced circuit (110-145) to be connected to the analog storage array (150) for detecting the signal stored in the analog storage array (150). Thereby, it is possible to improve the reliability of an EOM.
