Component for the linearity of the line deflection in a television receiver

摘要

In a line deflection circuit for a television receiver, a so-called linearity coil (11) for adjusting the linearity and an amplitude coil (10) for adjusting the amplitude coil are necessary in the path of the line deflection current. According to the invention, the linearity coil (11) is additionally used for setting the picture width. For the purpose, an additional adjustable magnetically active part (19) is allocated to the coil former (15) of the linearity coil, by means of which part the inductance (L) of the coil (14) can be varied. <IMAGE>
