A negative feedback amplifier has a close-loop gain Af=100 and an open-loop gain A=105. What is the feedback factor ?? If a manufacturing error results in a reduction of A to 103, what close-loop gain results? What is the percentage change of Af corresponding to this factor of 100 reduction of A?
a 60-kHz sinusoidal signal is applied to an amplifier with a gain of k=2. the circuit is built with an lm741 opamp with power supplies +-13V. find the largest amplitude the signal may have before it is limited by slew rate constraints.
