ダー。 A tape recorder that is connected to an audio cassette interface of a personal computer and records/plays back data signals transmitted from the personal computer in a frequency displacement method, the data signal being a first frequency signal consisting of a first frequency signal and a second frequency signal. Is it configured in frequency mode?
A detection circuit that detects whether the data signal is configured in a second frequency mode consisting of second and third frequency signals, a first filter that passes only the data signal consisting of the first frequency mode, and a data signal consisting of the second frequency mode. It is characterized by comprising a second filter that allows only the signal to pass through, and a switching circuit that is controlled by the detection output from the detection circuit and selects one of the filters that corresponds to the frequency mode of the data signal. tape recorder.
