In amplifiers using class B bias, illustrated in Fig. 5.3.1, there is no standing bias current (the quiescent current is zero) and due to this fact the transistor conducts for only half of every cycle of the sign waveform. This dramatically increases effectivity, compared with class A. Theoretically practically 80% efficiency can be achieved with this bias and in sensible circuits, efficiencies of 50% to 60% are possible.

The image modes had been good and like most 1080p TVs it supports 1:1 pixel mapping. The menus are good, but we discovered the edit channel checklist very cumbersome. Whereas we're talking about things we do not like, man this remote actually needs to be pointed at the underside right of the Television, -- even when you're a few feet from it -- maybe we need to test the batteries.
