ABSTRACT:
A TV signal receiving tuner which is small in size and inexpensive due to a reduced number of local oscillators. In the TV signal receiving tuner, a local oscillation signal output from a local oscillator is directly applied to a first mixer through a first programmable divider to receive a UHF TV signal, the local oscillation signal output from the local oscillator is applied to the first mixer after its frequency is divided to 1/3 by the first programmable divider to receive a VHF high-band TV signal, and the local oscillation signal output from the local oscillator is applied to the first mixer after its frequency is divided to 1/5 by the first programmable divider to receive a VHF low-band TV signal.
