Signal processing device and method, and digital broadcast receiving device, and method |
摘要 |
A signal processing device includes: a first converting unit for frequency-converting the input signal into a signal in a first frequency band; a filter for cutting off the frequency component outside a predetermined pass band; a second converting unit for frequency-converting the signal from the first frequency band to a second frequency band; third converting unit for converting the signal in the second frequency band into a signal in a third frequency band coinciding with the pass band; an oscillating unit for oscillating a signal used for frequency conversion of the third converting unit; and a detecting unit for detecting a frequency error between oscillation frequency of the signal oscillated by the oscillating unit and frequency of a signal used for frequency conversion from the second frequency band to the third frequency band coinciding with the pass band, and outputting an error signal indicating the frequency error.
