Digital signal processing system and multi-signal connector thereof

A digital signal processing system for receiving radio frequency signals and converting the radio frequency signals into digital signals displayed on a display, the digital signal processing system comprising:

• a signal receiver for receiving a first radio frequency signal;
• and
• a multi-signal connector electrically connected to the signal receiver, the multi-signal connector comprising:
• a circuit board;
• a plurality of signal pins disposed on the circuit board, the signal pins comprising a first radio frequency signal pin, a first ground signal pin and a plurality of digital signal pins, wherein the first radio frequency signal pin is capable of transmitting the first radio frequency signal;
• a first tuner disposed on the circuit board for receiving the first radio frequency signal via the first radio frequency signal pin and converting the first radio frequency signal into a first digital signal;
• and
• a first demodulator disposed on the circuit board for receiving the first digital signal from the first tuner and converting the first digital signal into a moving pictures experts group (MPEG) signal compatible with an MPEG-2 or MPEG-4 standard, the first demodulator configured to transmit the MPEG signal via the digital signal pins to the signal receiver to be processed;
• wherein the first ground signal pin is disposed between the first radio frequency signal pin and the digital signal pins for reducing interference and noise between the first radio frequency signal and the MPEG signal, wherein the first radio frequency signal pin, the first tuner, first demodulator, the plurality of digital signal pins, and the first ground signal pin are integrated on the circuit board.
