program. This impedance bridge allows you to automatically measure inductors, capacitors, resistors, input impedances, audio transformers, negative resistances and more, at a wide range of audio fre-quencies. It has outstanding capabilities and accuracy. The cost of the project is less than $1 (yes…one dollar!), not counting the PC and power supplies.
What is Impedance in Audio? Input and Output …
https://virtuosocentral.com/what-is-impedance-in-audio/
In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance measurements, namely input, and output impedances. More on that later.

Digital Impedance Bridge B. C. Waltrip and N. M. Oldham, Senior Member, IEEE Abstract- An impedance bridge that compares two-terminal standard inductors to characterized ac resistors in the frequency range of 10 Hz to 100 kHz is described. A dual-channel, digitally-synthesized source and sampling digital multimeter are used to

Understanding Impedance - Sound on Sound
https://www.soundonsound.com/techniques/understanding-impedance
In audio input and output circuits the impedances are principally resistive to make interconnection easier — the impedance won't change too much over the range of audio frequencies. However, the impedance to radio frequency (RF) signals will often be very different to that at audio frequencies in order to keep RF interference out.

No. STX-107 Moy,1968 ,u. THE UNIVERSAL IMPEDANCE BRIDGE 1. Why can" we simply measure L and C instead of L, or Lp and C, or Cp7 2. Why does a universal impedance bridge measure D and Q instead of the equivalent series resistance or parallel conductance? 3. When is the null good enough to take advantage of the accuracy buil~ into the bridge? 4, When does the nulling …

For example, on the 500 and 2,500 mV ranges the input impedance is greater than 1 Giga-Ohm. On the 5.0 to 5,000 volt ranges, the input impedance ranges from 10 to 10.5 Meg-Ohms. If the input impedance is extremely high, looking at a capacitive load like C5 in Figure 6 may cause problems, so resistor R4 was added. It may not be needed in some cases, and if omitted, will …
