Question
The closed loop gain can be calculated by adding one to the ratio between two types of this quantity. For 10 points each:
[10e] Name this quantity, which measures the opposition to current flow. This quantity is measured in ohms.
ANSWER: resistance
[10m] The “closed loop” variety of these circuit elements includes a negative feedback loop, which allows more precise voltage gain. A triangle represents these non-diode circuit elements.
ANSWER: operational amplifiers [or op amps; accept closed-loop operational amplifiers or closed loop op amps; prompt on amplifiers]
[10h] An ideal operational amplifier has an infinite value for these signals’ namesake “rejection ratio.” For a grounded two-wire cable, these signals always have equal phase and amplitude.
ANSWER: common-mode signals [accept common-mode rejection ratio; prompt on CMRR]
