Why differential amplifiers are preferred for instrumentation and industrial applications?
A. Input resistance is low
B. Produce amplified output
C. Amplify individual input voltage
D. Reject common mode voltage
Answer:A
Why differential amplifiers are preferred for instrumentation and industrial applications?
A. Input resistance is low B. Produce amplified output C. Amplify individual input voltage D. Reject common mode voltage
Explanation: Differential amplifiers are preferred in these applications because they are better able to reject common-mode voltage than single input circuits and present balanced input impedance.
