Even though it has a very similar impedance to telephone cable, the nominal impedance is rated at 100 ?.
12.
Cable with 75 ? nominal impedance has been in use from an early period in telecommunications for its low loss characteristic.
13.
It is, however, still perfectly possible for the low frequency impedance to actually be lower than the nominal impedance.
14.
The nominal impedance rating of consumer loudspeakers systems can aid in choosing the correct loudspeaker for a given amplifier ( or vice versa ).
15.
This filter transformed to a band-pass filter will have an impedance equal to the nominal impedance at resonance rather than low frequency.
16.
Depending on the field of application, nominal impedance is implicitly referring to a specific point on the frequency response of the circuit under consideration.
17.
This nominal impedance of filters will generally be the same as the nominal impedance of the circuit or cable that the filter is working into.
18.
This nominal impedance of filters will generally be the same as the nominal impedance of the circuit or cable that the filter is working into.
19.
Nominal impedance " is " used, however, to characterise the transducers of an audio system, such as its microphones and loudspeakers.
20.
The test consists of transmitting an analog sinusoidal signal at the frequency of 1004 RMS ) is applied to a telephone line with 600 Ohm nominal impedance.
