Device for receiving a RF signal with loop-through output and method for looping a RF input signal through a device for receiving RF signals

Abstract

A device for receiving a RF signal (1; 21) with loop-through output (16) is provided. The device comprises: an input (3) receiving a RF input signal (2); an analog- digital converter (8) converting the RF input signal (2) to a digital signal (9); a digital signal processing unit (10) digitally processing the digital signal (9); a digital-analog converter (14) converting the processed digital signal (13) to a loop-through RF signal (15) corresponding to the RF input signal (2); and a loop-through output (16) outputting the loop-through RF signal (15).

Description

technical field

[0001] The present invention relates to a device for receiving an RF signal with a looped output and a method for looping an RF input signal by receiving the RF signal. More particularly, the present invention relates to an apparatus for receiving an RF signal having a loop output, wherein the RF input signal is digitized before being output as a loop RF signal at the loop output. Background technique

[0002] In the context of this application, an RF signal is to be understood as an analog signal comprising a plurality of frequencies, for example, frequencies in the band 45 to 1040 MHz. A large number of different devices for receiving RF (Radio Frequency Signals) signals can be found on the market. Examples of such devices are TV tuners for cable modems, DVD recorders, set top boxes, USB dongles, PC add-on cards, TVs and other RF equipment. In these devices, an RF input signal is applied to the input of the device and the device is adapted to sample the R...
