Abstract

PURPOSE: To select digital data, which is mixed with sound, with a simple circuit by utilizing the frequency band of digital data and its regularity.
CONSTITUTION: Sound information and digital information from recorder 1 are supplied to level controller 3 and FM demodulator 12, and signals over a prescribed level are detected in 5 and rectified in 6 through BPF 4, and an input over a set level is outputted by comparator 7, and sound or digital signals are discriminated in confirmation circuit 8. Then, gate 10 is made conductive by the discrimination output, and digital data from FM demodulator 12 is supplied to CPU 9.
