Paper Abstract

In electronic amplifiers of image signal in television cameras is sometimes used complex antinoise correction. It effectively suppresses self-noise of the amplifier. The essence of the correction consists in including an inductive choke in the input circuit of the amplifier, due to that high-frequency impedance is increased and, together with it, the level of the signal components in this region of frequencies relative to the self-noise of the amplifier. Careful analysis of the circuits of the complex antinoise correction with the account of the losses in the input circuit has allowed to get new conclusions, which can be useful in constructing the low-noise video amplifiers.
