M-982-02 Description
The M-982-02 is an integrated circuit precise tone detector for special-purpose use in automatic following of switched telephone calls. The circuit uses lowpower CMOS techniques to provide the plete filtering and control required for this function. The basic timing of the M-982-02 is designed to permit operation with almost any progress tone system.The use of integrated circuit techniques allows the M-982-02 to pack...
