That is, the system has low outputimpedance in both the low- and high-frequency range. The outputimpedance reaches the maximum value around the system high cutoff frequency. In contrast, modern transistor amplifiers can have very low outputimpedance, enabling lower impedance headphones. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One half is impedance-scaled to the input impedance and the other is scaled to the outputimpedance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The second measure is the outputimpedance of the current source or equivalently its inverse, the output conductance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The outputimpedance of the pair is now halved. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Such a theoretical device would have a zero ohm outputimpedance in series with the source. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Valve outputs require an output transformer to match the very high outputimpedance and voltage of the output valves to this lower impedance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A generator with very high outputimpedance is effectively a temperature sensor, not a generator. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One can however measure its input or outputimpedance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This reduces their gain, but improves their linearity, input impedance, outputimpedance, and bandwidth, and stabilises all of these parameters, including the closed-loop gain. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Amplifiers are not ideal; they also have some outputimpedance that limits the amount of power they can provide. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. More importantly, low outputimpedance can reduce distortion by improving the control that the source has over the transducer. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A power amplifier may have a rated impedance of 8 ohms, but the actual outputimpedance will vary depending on circuit conditions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Because the outputimpedance of the op-amp is very low, it drives the load as if it were a perfect voltage source. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Consequently, newer amplifiers are based on designs with relatively low outputimpedance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Well-designed amplifiers have low outputimpedance so that this generated signal has little effect on the amplifier. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A group of a transistors parameters sufficient to predict circuit gain, input impedance, and outputimpedance are components in its small-signal model. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Their high outputimpedance matched the high input impedance (typically about 10 megohms) of the vacuum tube input stage well. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The actual outputimpedance for most devices is not the same as the rated outputimpedance.
