In a TV transmitter, a series circuit has an impedance of 3 kΩ and a total current of 50 mA. If the voltage across the resistor is 80 V, what is the power factor of the circuit?
A three-stage amplifier is shown. The operating bandwidth is 500 KHz at a temperature od 25 degrees C. The output load is 1000 ohms. calculate the total NF as a number, calculate the output noise power, and calculate the output noise voltage.
A full-adder is more generally known as a (3,2) counter, in that itadds three bits, producing a two bit result (sum and carry). A (4,3) counter sumsfour-bits, producing a three-bit result, and a (10,4) counter sums ten-bits, producing afour-bit res..
Design the simplest circuit that has three inputs x1,x2, x3, which produces an output value of 1whenever two or more of the input variables have the value 1;otherwise, the output has to be 0.
Non-essential electrical loads have been secured and the remaining electrical loads are required to be operating 24 hours a day. What are some of the measures you can take to reduce the overall warehouse power consumption? Can 100% efficiency e..
A charge density of ohm Coulombs per square meter is uniformly distributed over a thin and very long cylindrical shell of radius a. You want to know the electric flux density field D and the electric field E generated by this charge at all points ..

The open-loop gain of a compensated op-amp is measured as follows:5.1´103 at100 kHz and 8.3´103 at10 kHz. Calculate its 3dB frequency, its unity-gain frequency, and its dc gain.
A temperature sensor produces 10 mV for each degree Fahrenheit. Determine the error in temperature reading if 20 mV of noise is added to the sensor output signal when the temperature is 70 degrees.
A dc series motor has a armature current of 10A at full load. The motor terminal voltage is 300V. The armature and field resistances are 2 ohm and 3 ohm respecitively. The motor speed at full load is 250 rpm. Calculate the starting torque of the m..
With respect to sinusoidal signals, explain the difference between the way we normally define "amplitude" and the "amplitude" measurement on an oscilloscope. Also, How does the amplitude setting on a function generator relate to these
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
