COLLOCATIONS FROM CORPUS
■ ADJECTIVE
high
▪
This provides a relatively high input impedance looking into their bases and a low output impedance at the emitters.
▪
Its high input impedance means that it does not load a signal source which it copies at its output.
■ NOUN
input
▪
This provides a relatively high input impedance looking into their bases and a low output impedance at the emitters.
▪
The input impedance also deteriorates at high frequencies.
▪
At low-enough frequencies to satisfy, the input impedance is virtually which is becoming very large.
▪
The term iterative impedance is applied to a load that renders the input impedance of an asymmetric section equal to it.
▪
Negative series-inserted feedback always raises the input impedance while negative shunt-inserted feedback reduces it.
▪
Its high input impedance means that it does not load a signal source which it copies at its output.
output
▪
Finally, is the small-signal, complex, output impedance when the input is open circuit to signals.
▪
This provides a relatively high input impedance looking into their bases and a low output impedance at the emitters.
▪
The output impedance is about 0.02 ohm at the 5V end and 0.1 ohm at the 15V end of the range.
EXAMPLES FROM CORPUS
▪
Ideally, any alternating voltmeter should possess infinite impedance and any a.c. meter negligible impedance.
▪
Its high input impedance means that it does not load a signal source which it copies at its output.
▪
Parameters and are in fact dimensionless while and respectively exhibit impedance and admittance dimensions.
▪
The impedance of the battery alone is enough to regulate their input.
▪
The output impedance is about 0.02 ohm at the 5V end and 0.1 ohm at the 15V end of the range.
▪
The phasors representing the e.m.f. and potential difference across impedance Z then have lengths in the same proportion to and respectively.
▪
Transformer coupling of the source and/or detector to the Wheatstone network is often adopted to match impedance levels or for isolation purposes.
