Abstract
The present invention relates to a signal processing device and a signal processing method that are capable of processing various types of signals. The signal processing device comprises a frequency detecting unit detecting a frequency of a data signal by checking synchronization between the data signal and a reference signal, an oscillation unit supplying the reference signal to the frequency detecting unit, a frame detecting unit detecting a frame organizing the data signal, and a control unit changing a frequency of the reference signal supplied by the oscillation unit to take frequency synchronization between the data signal and the reference signal in checking the synchronization by the frequency detecting unit, and setting information of the frequency, of which the frequency synchronization has been taken, in the frame detecting unit.
