Summary:A channel receiving apparatus includes: a first modulating device converts a first channel into a first predetermined frequency according to a first oscillating signal and a second oscillating signal; and a second modulating device converts a second channel into a second predetermined frequency according to a third oscillating signal and a fourth oscillating signal; wherein the first oscillating signal has a first frequency, the second oscillating signal has a second frequency, the third oscillating signal has a third frequency, and the fourth oscillating signal has a fourth frequency, when the third frequency is substantially equal to the first frequency, the third oscillating signal is arranged to be shifted by a predetermined frequency range to have a fifth frequency different from the first frequency, and when the second frequency is substantially equal to the first frequency, the second frequency and the first frequency are shifted by the predetermined frequency range.
