Q. Can you explain Noninverting Amplifier?
It is called "noninverting" because there is no sign inversion. A typical circuit is shown in Figure. With a finite op-amp gain Ao,
Since the ideal op amp draws no current,
i1 = i2
Also, as seen from Figure,
v2 = vi
In equating Equations, one gets
which is the gain of an ideal voltage follower. The same result applies if R1 →∞ (i.e., open circuit) for any finite R2.
Design a combinational logic circuit to convert XS3BCD code in to the standard 8421 BCD code.
A DC shunt motor rotating at 1560 RPM is supplied from a 240-V source. The line current supplied to the motor is equal to 27 A. The shunt field resistance of the motor is equal to
Q. What are frequency response curves? How are they made? Every amplifier has a frequency-response curve associated with it. They provide a "picture" of the performance of an a
The five stages of DLX pipeline is:- ? Operand location ? Number of explicit operands per instruction ? Operand storage in the CPU ? Operations ? Type and size of o
