BIDIRECTIONAL DEFLECTOR DRIVER FOR VIDEO DISC |
摘要 |
<p>-13- RCA 74,513 A bidirectional pulse generator for driving a video disc stylus deflector. Responsive to a deflection pulse a charge integrator has its input connected to a polarity selectable current source. The integrator generates a ramped potential output signal having an amplitude proportional to the deflection pulse width and a slope related to the current polarity. Upon termination of the deflection pulse a feedback loop is closed around the integrator to rapidly reset the output potential of the integrator to one of two pre-pulse output amplitudes. A direction control selects the current source polarity and controls the pre-pulse output amplitude and thereby the relative polarity of the output pulse.</p> |
