Abstract:
A television signal receiving apparatus cooperating with a front-end circuit in a frequency division full-duplex satellite television system is provided. A digital-to-analog conversion circuit receives a request signal to be sent to the front-end circuit, and outputs an analog request signal. A multi-node low-pass filter has a first node, a second node and a third node. The first node is electrically coupled to an output end of the digital-to-analog conversion circuit. The third node is electrically coupled to the front-end circuit. The multi-node low-pass filter filters out high-frequency signals coupled from the first node and the third node to the second node, and further filters out high-frequency signals coupled from the first node to the third node. A command parsing circuit receives a filtered signal from the second node, and processes and parses the filtered signal.

Claim (Index 1):
A television signal receiving apparatus cooperating with a front-end circuit in a frequency division full-duplex satellite television system, the front-end circuit providing a television signal and a communication signal, the television signal receiving apparatus comprising:\n a request generating circuit, comprising: a signal processing circuit, generating a string of data bits representing a request signal; a mixer, performing mixing on the string of data bits to generate a mixing result; a digital-to-analog conversion circuit, performing digital-to-analog conversion on the mixing result to generate an analog request signal; and a multi-node low-pass filter (LPF), having a first node, a second node and a third node, the first node receiving the analog request signal, the third node electrically coupled to the front-end circuit, the multi-node LPF filtering out high-frequency signals flowing from the first node and the third node to the second node and further filtering out high-frequency signals flowing from the first node to the third node, a cut-off frequency of the multi-node LPF being associated with a carrier frequency of the analog request signal and a carrier frequency of the communication signal; a command parsing circuit, electrically coupled to the second node of the multi-node LPF, receiving a filtered signal from the second node, and processing and parsing the filtered signal; and a television signal processing circuit, receiving and processing the television signal provided by the front-end circuit.
