ABSTRACT:
A television line output circuit includes a first sawtooth network with a diode (D), a trace capacitor (Ct), a retrace capacitor (Cr) and a line deflection coil (Ly), and a second sawtooth network with a diode (D'), a trace capacitor (C't), a retrace capacitor (C'r) and a coil (L'). The diodes (D, D') are connected in series and the two sawtooth networks connected across a line output transistor (Tr). A first modulation source (M1) is connected across the trace capacitor (C't) in the second sawtooth network to modulate the line deflection current to overcome East-West pin-cushion distortion. A resistor (R) of low ohmic value is connected between the anode of the diode (D') in the second sawtooth network and earth and a second modulation source (M2) is connected across this resistor (R). The second modulation source (M2) provides a signal dependent on beam current to correct for display errors at line frequency rate as they occur.
