n a symmetrical T attenuator pad, each series arm has a resistance of 35? and the shunt arm has a resistance of 110?. Determine:
a. the characteristic impedance
b. the insertion loss when feeding a matched load
c. the A B C D constants of the circuit
three single-phase transformers rated at 250kVa, 7200V/600, 50Hz, are connected in wye-delta on a 12470V, 3 phase line, if the load is 450kVA, calculate the current in the incoming and outgoing transmission lines and in the primary and secondary w..
Using SR Flip-flops and NAND gates, design a system that outputs 1 if it takes an even number of clock cycles to recognize the pattern 11-0-101. Otherwise it outputs 0.
Create the Walsh code matrix for a W16. (c) For IS-95, on the forward link, list the Walsh code assigned to the various logical channels (hint: there are 64 Walsh codes)
Knowledge about Circuit Analysis, A 5.1K resistor is connected between the cathode of a 6.2V zener diode and a 12V power supply
Determine log10 0.2 = log10 18/90, and compare to log10 18 - log10 90.
For the amplifier in Fig. P4.20, the maximum value of VS is 2 V and the op-amp can deliver no more than 100 mA. (a) If +-10 V supplies are used, what is the maximum allowable value of R2 (b) Repeat for +-3 V supplies.
A) Write the KCL expression for this circuit and set it equal to zero. B) Find the voltage of Vo. C) Use your value of Vo. The final step is to use the inverse phasor-transform operation to transform this value.
A filter with a great deal of attenuation must be placed in an amplifier chain. Ignoring all considerations other than the desire to minimize noise figure, would it be preferable to put the filter before or after a low noise amplifier Why
On a spacecraft two engines fire for a time of 541 s. One gives the craft an acceleration in the x direction of ax = 4.90 m/s2, while the other produces an acceleration in the y direction of ay = 7.60 m/s2.
The electric motors unmanned drones use transformers to produce sufficient current to move the flight surfaces. Due to the weight restrictions of the vehicle, the transformers use a ceramic rather than iron, the ceramic has a permeability of mu = 4..
