RF signal recording / reproducing device, RF signal recording apparatus, RF signal recording / reproducing method, and RF signal recording method

摘要

In the RF signal recording / reproducing apparatus and the RF signal recording / reproducing method, it is possible to reduce the possibility of the waveform deviation and the spurious occurrence due to the phase shift during reproduction.The RF signal distributed at least in two systemsFrequency conversion is performed for each distributed system.The IF signal output for each system isAmong the pass bands in which the IF signal is converted to the frequency before conversion of the IF signalAdjacent ones are filtered by a plurality of band pass filter portions overlapping with the band over the maximum modulation width of the RF signal;Filtered IF signalThe digital RF memory units 41 to 4N are provided for each of the band-pass filter sections.Diagram
