Explain Acceptance cone?
The fibre air - core interface is display below:
In this figure Omax is the maximum angle, inside that the rays undergo total internal reflection and propagate by the fibre. The rays along with angle greater than Omax is do not obey the total internal reflection, these rays eventually lost by radiation. Therefore we have an acceptance cone as display below along with conical angle of 2 Omax.
The angle Omax is known as acceptance angleOmax = sin- [(n12 -n22)]1/2 (suppose that the outer medium is air)
Positive Clippers The shunt connected positive clipper, in which the diode conducts for positive half cycle and hence, the output is a straight line. During the negative half c
Q. Amplifiers with Feedback? Almost all practical amplifier circuits include some form of negative feedback. The advantages gained with feedback may include the following: •
A three-phase transposed line is composed of one conductor per phase with flat horizontal spacing of 11 m as shown in Figure 1(a). The conductors have a diameter of 3.625 cm and a
Q. How can a JFET be used as a constant current source? Explain from the drain characteristics. As the VDS voltage is increased from 0 to a few volts, the current will increase
Auxiliary Carry Fla - Registers If carry is generated from D 3 to D 4 in the accumulator after any arithmetical or logical operations. Auxiliary carry flag (AC) is set
Q. What is Balanced Budget? Balanced Budget: An annual budget (like for a government) in that revenues perfectly offset expenditures, so that there is neither a deficit nor a s
For the network shown in Figure, find the current in each resistor by means of nodal analysis.
Task 1 Use basic circuit theory to convert the "T" circuit below into the equivalent "π". Hint: Remember to disconnect the voltage source and the load. Task 2
How the interrupts can be masked/unmasked in 8086? The 8086 interrupt priorities are concerned; software interrupts have the highest priority, followed by NMI followed by INTR.
