Analog-to-digital-converting and suppressing system

Systems ( 20, 22 ) with analog-to-digital-converters ( 5 ), for use in receivers ( 30 ) comprising tuners ( 31 ) and channel decoders ( 32 ), comprise analog filters ( 1, 2 ) located before the analog-to-digital-converters ( 5 ). The analog filters ( 1, 2 ) at least partly suppress the analog wanted...

description Systems ( 20, 22 ) with analog-to-digital-converters ( 5 ), for use in receivers ( 30 ) comprising tuners ( 31 ) and channel decoders ( 32 ), comprise analog filters ( 1, 2 ) located before the analog-to-digital-converters ( 5 ). The analog filters ( 1, 2 ) at least partly suppress the analog wanted signal and the analog unwanted signal. Compensators ( 3, 4 ) compensate the digital output signal of the analog-to-digital-converters ( 5 ) for the at least partly suppressing of the analog wanted signal. As a result, the analog unwanted signal in an adjacent channel could now be suppressed better than before, at the cost of also partly suppressing the analog wanted signal in a wanted channel. The compensators ( 3, 4 ) restore the wanted signal.
