Q. The model of an elemental length of a lossy transmission line is shown in Figure
(a), along with its parameters, where R is series resistance per unit length, L is series inductance per unit length, G is shunt conductance per unit length, and C is shunt capacitance per unit length.
The characteristic impedance ¯ Z0 of the line is given by
where α is the attenuation constant (nepers per unit length) and β is the phase constant (radians per unit length). The ac steady-state solution for the uniform line reveals the voltage on a matched line ( ¯ ZL = ¯ Z0) to be ¯ E(x) = ¯ ES e-¯ γx= ¯ ES e-αx e-jβx , where ¯ ES is the sending-end voltage and x is distance along the line from the sending end.
Q. A magnetic force exists between two adjacent, parallel current-carryingwires. Let I1 and I2 be the currents carried by the wires, and r the separation between them.
Thermal noise This is the most significant noise in an ampli?er. It is produced by random movements of electrons in the resistors. This is caused by the ?uctuations in the volt
Q. A silicon diode is forward-biased with V = 0.5 V at a temperature of 293 K. If the diode current is 10 mA, calculate the saturation current of the diode.
Q. Use the node-voltage method to find the current I through the 5- resistor of the circuit of Figure.
when MT 2 and Gate is Negative In this case gate current flows through P 2 N 3 junction. Junction N 1 P 2 forward biased hence the triac starts conduction through P
