Abstract
1317700 Transistor threshold circuits ROBERT BOSCH FERNSEHANLAGEN G.m.b.H. 30 Dec 1971 [31 Dec 1970] 60726/71 Heading H3T An arrangement, Fig. 2, (not shown), for providing two variable reference voltages for an amplitude range discriminator comprises a chain of resistors with one end connected to a first output and a current source, tapping points on the resistor chain being connected to two switches which selectively connect any tapping to a reference potential and to a second output respectively. The two outputs U 1 , U 2 are applied to respective clamp circuits 33, 35 34, 36 the outputs from which are connected to trigger circuits 37, 38, 41, 42 which produce a "1" output when an input video signal at 32 lies between the levels U 1 , U 2 , and a "O" output when the signal at 32 is outside these limits.
