A signal has the double-sided amplitude and phase spectra shown in Figure 2.34. Write a time-domain expression for the signal.
An NMOS device operating with a small drain-source voltage serves as a resistor. If the supply voltage is 1.8V, what is the minimum on-resistance that can be achieved with W/L=20
a. The input G=0, H=0 is not allowed for this flip-flop. Why b. What is the excitation table for the GH flip-flop c. Use GH flip-flops to construct a counter to count the following sequence: 000 -> 001 -> 010 -> 100 -> 000
In a satellite radio system, 128 stations of stereo quality are to be packaged in one data stream. For each station, two(left and right) signals of bandwidth 15,000 hz are sampled, quantized, and binary coded into PCM signals.
An engineer attempts to build a remotely actuated door lock for asecurity operation. The door is powered by an electromagnetic actuator whose coil can be modeled as a 500Ω resistor .The actuator requires a minimum of 100mA of current for reliable ..
A certain microphone is capable of delivering 0.5V when someone clap their hands at a distance of 20ft. A particular electronic switch has a Thevenin equivalent resistance of 670ohm and requires 100mA to energize.
The current is the flow of electrons through conductor ,and voltage is the force that exerted on electrons to flow through the conductor, then why in many electric circuit the voltage is very high while current is less or vice-versa.
when the load is removed from the generatorthe magnitude of the terminal voltage is 34500V. the generator feeds a delta-connected load through a transmission line with an impedence of 0.8+j6.4. the per-phase impedence of the load is2877-j864.
A small magnetic needle, which is free to turn slowly in a horizontal plane, is placed at the center of the coil in question (6). Show that it will set at an angle \(\phi\) to B where \(cot(\phi) = 4R/(\pi n^2 \mu_{o}\omega a)\)
If an ice cream cone is 6 inches tall and its rim has a diameter of 2 inches, determine the weight of ice cream that can fit in the cone assuming the ice cream above the cone is a perfect hemisphere.
A Building produce 400 V at 200 A. using individual photovoltaic cells that each produce 0.5 V at 1 A . Include a schematic diagram of your design idea. How many photovoltaic cells are needed for your design.
State the meaning of permeability, write down the expression for the permeability of free space, and indciate how it was developed from the Biot-Savart Law.
A 1.0 dc voltage source is connected across a 10 ohm resistor. What is the current through the resistor if (a) the voltage source is ideal (b) the voltage source has internal resistance 0.1 ohm (c) internal resistance 1.0 ohm
