terminal, said first pair of transistors each having a
terminal that is connected with a first junction, said second
pair of transistors each having a terminal that is connected
with a second junction; the first and second junctions being
galvanically connected with the first and second output
terminals, respectively; and
second sub-assembly connected between said junctions and
in circuit with each transistor’s control terminal, said
second
sub-assembly comprising a tuned circuit and a third sub-
assembly functional to cause said transistors to switch on and
off in a time-pattern operative to cause said output voltage
to have said periodic and substantially sinusoidal waveshape.
The examiner relies on the following references:
Burke 4,277,726 July 07, 1981
Walden 4,346,332 Aug. 24, 1982
