ABSTRACT:
A reset signal generating part outputs reset signals RV and RD to a signal discriminating part, based on an output from a 2100 Hz detecting part which detects whether or not a tone of 2100 Hz exists in an input signal. When the 2100 Hz tone is detected, the signal discriminating part firstly resets a discrimination state at "speech" and secondly sets the discrimination state at "data" based on the reset signal. Therefore, a signal discrimination apparatus, wherein it is possible to reset the discrimination state at "speech" at the beginning of a facsimile call even when no call control information is received, can be provided.
