(4) Tuner Block

A.  Low pass filter & high pass filter
This consists of IF trap circuit and UHF & VHF separation circuit. If the input signal is IF(45.75MHz), this filter
prevents interference.

B. Single tune & RF AMP
This consists of a filter circuit, RF AMP, impedance conversion circuit, image trap and a single tuning circuit. It
prevents noise and other interference signals. RF AMP is controlled by AGC come from IF DEMOD block. 

C. Double tune
It consists of a double tuning circuit to improve rejection characteristic which results in a better band characteris-
tic.

D. MOP IC (Mixer, OSC, PLL)
It consists a VHS and UHF OSC and mixer circuit. We applied a double balance mixer to have better rejection
characteristic, it shows especially various beat characteristic. 
It serects channels and contains charge pump band driver. The minimum step standard frequency 27.97KHZ.
