WebMay 22, 2024 · With a transformer turns ratio of (a + 1): 1, the overall voltage gain of the transformer-amplifier combination is the same as that of the follower connection, while the input impedance is Vi I ″ i = Zi(1 + a)2 This value greatly exceeds the value obtained with the follower for large amplifier voltage gain. Figure 2.19 Unity-gain amplifiers. The characteristic impedance or surge impedance (usually written Z0) of a uniform transmission line is the ratio of the amplitudes of voltage and current of a single wave propagating along the line; that is, a wave travelling in one direction in the absence of reflections in the other direction. Alternatively, and … See more The characteristic impedance $${\displaystyle Z(\omega )}$$ of an infinite transmission line at a given angular frequency $${\displaystyle \omega }$$ is the ratio of the voltage and current of a pure sinusoidal … See more In electric power transmission, the characteristic impedance of a transmission line is expressed in terms of the surge impedance loading (SIL), or natural loading, being the power loading at which reactive power is neither produced nor absorbed: See more This article incorporates public domain material from Federal Standard 1037C.
