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.
what is serveces of operating system?
Q. Linear and position invariant? Assume that the model illustrated below is linear and position invariant. Also the noise and the image are uncorrelated. Show that the powe
A microstrip antenna system operating at 915MHz must be designed using Rogers RO3010 substrate with the thickness of 0.635mm.
dear sir, when i am going to simulate my model in matlab i am getting the following error : the derived input for the integrator is inf or nan at time xxxxx. try to reduce the step
Voltage and Frequency Control Methods In this control method the ratio of voltage to frequency is kept constant so that the flux remains constant. The voltage at varia
The mechanical power produced at the armature of a motor is: P = T a . (power is in watts if torque is N.m and in rad/sec). Some of this will be lost due to friction and
