In the Doherty amplifier of Figure, the value of α is chosen equal to 0.5. Plot the waveforms at x = 0 and x = λ/4, assuming Z0 = RL.
Figure:-
Design an excess-2 code converter to drive a seven-segment indicator . the four inputs to the conducter circuit is (A,B,C, andd) represent it in Excess-2 code decimal digit. the inputs aredigits 0-9, so the six unused combinations are dont cares.
A rotating machine, such as turbines or compressors, is vibrating and transmitting large forces to the ground. This vibration might be due to shock or unbalanced mass of the rotor.
Use Smith Chart: A 100 Ohm air-coaxial transmission line is measured to have an input impedance of 100 + j100 Ohms. If the system is operated at 100 MHz and is one meter long, what is the terminating load impedance
Consider a system for which the output voltage is vout(t) = vin(t) + vin(t - 10^-3). (In other words, the output equals the input plus the input delayed by 1 ms). Given that the input voltage is vin(t) = Vmax*cos(2*pi*f*t),
Determine the rms output voltage, the rms source current, the rms and average currents through SCRs, and the power factor.
A lossless transmission line with the electrical length of l = 0.3 lamda and the characteristics impedance of Z0 = 75 is terminated with a complex load ZL = 30 -j20 calculate the reflection coeficient at the load, the SWR on the line
show that for a square matrics the linear dependence of the row vectors imples the column vectors.conversely for a non square matrics either row vectors or column vectors are linear dependent.
Three identical inductors are connected in series to a 240v 1000hz line, and the circuit current is .6A What is the inductance of each inductor
What is the electric potential at the center of the square?
Identify one or more experience goods. Identify one or more search goods. How does the retailing of experience goods differ from the retailing of search goods? Do these differences help consumers?
In transformer designs, often you can find an air gap in the core. In all the electric machines, there is an air gap between the stator and rotor. In both cases, flux will go through both core material and the air gap.
Given: A permanent magnet DC motor has a machine constant, Kv = 0.5 V-s. The no-load torque is 1.0 Nm. Assume mechanical torque loss is a constant. Determine the mechanical power developed by the unloaded motor at 1250 rpm.
