Abstract
The present disclosure relates to a signal processing device and an image display apparatus including the same. A signal processing device according to an embodiment of the present disclosure includes a sampler to downsample a baseband signal; a memory to store the downsampled data; a frequency shifter to read the data in the memory and shift the read data in a frequency domain; a symbol rate calculator to calculate a symbol rate based on the shifted data; a first offset calculator to calculate a first carrier frequency offset based on the calculated symbol rate; a second offset calculator to calculate a second carrier frequency offset based on the calculated first carrier frequency offset; and an offset compensator to compensate for the second carrier frequency offset. Accordingly, a time up to the demodulation completion may be shortened based on the baseband signal.
