Title:
FULL-BAND RECEIVER AND TELEVISION TUNER
Document Type and Number:
WIPO Patent Application WO/2019/173955
Kind Code:
A1
Abstract:
A full-band receiver and a television tuner, relating to the technical field of signal processing. The full-band receiver comprises a single-to-dual circuit for converting a television signal into a first differential signal, a resistor attenuation network for attenuating the first differential signal, and a differential amplifier for amplifying a second differential signal, the gain of the resistor attenuation network and the gain of the differential amplifier being adjustable. The technical solution above facilitates improvement of the anti-interference performance and linearity of a circuit, thus improving the signal bandwidth that can be processed by the full-band receiver.
