Show moreA video playback amplifier with frequency compensation, employing a transistor amplifier having a relatively low input impedance, for example, wherein the input transistor of said amplifier is in common-base configuration, and an inductive transducer having a relatively low impedance operatively connected to said amplifier with the impedance of the transducer differing from that of the amplifier input by an amount and in such direction that the inductive reactance of the transducer and the low input resistance of the amplifier produce a current into the amplifier which is substantially constant over at least the midvideo frequency range.
