0, 299 ( U R - U Y ) + 0,587 ( U G - U Y ) + 0,114 ( U B - U Y ) = 0<br />
0,587 ( U G - U Y ) = - 0,299 ( U R - U Y ) - 0,114 ( U B - U Y )<br />
( U - U ) = - 0,299<br />
0,587 ( U - U ) - 0,114<br />
G Y R Y<br />
0,587 ( U B - U Y )<br />
( U G - U Y ) = - 0,51 ( U R - U Y ) - 0,19 ( U B - U Y )<br />
Maka bila rangkaian mencampur 30% (U R - U Y ) dengan 11% (U B - U Y)<br />
<strong>dan</strong> polaritasnya berlawanan diperoleh (U G - U Y ) sehingga hanya<br />
mengirim (U B - U Y ) <strong>dan</strong> (U R - U Y ) dengan mudah diperoleh (U G - U Y ).<br />
Dalam normal PAL sinyal (U B - U Y ) disebut sinyal U <strong>dan</strong> (U R - U Y )<br />
disebut sinyal V. Sinyal tersebut dipancarkan pada bi<strong>dan</strong>g frekuensi 5<br />
MHz <strong>dan</strong> lebar bi<strong>dan</strong>g masing-masing adalah 1,3 Mhz.<br />
