1 .What is the totem-pole output stage? What are its advantages?
2. What are the basic differences between buffered and unbuffered CMOS devices? How is a buffered NAND usually implemented in 4000B-series CMOS logic?
Try to develop a circuit such as that used for the representation of signals in Illustration 38 - transition from a line spectrum to a continuous spectrum. Only the frequency, not the pulse length should be variable.
Suppose that a family of logic gates considers the output ranges of [0 - 0.2V] as "0" and [3.1V-3.3V] as "1". What are the reasonable input ranges for "0" and "1"? (a) "0": [0.1 - 0.4V], "1": [2.3V - 3.3V]; (b) "0": [0-0.3V], "1": [2.8V - 3.0V]; (..
a) Draw the State Transition diagram. b) Derive the State Table for implementing the counter using D flip-flops. c) Use K-maps to minimize the inputs to the D flip-flops. d) Show the final circuit.
An eight-pole, 25-kW, 120-V dc generator has a duplex lap-wound armature which has 64 coils with 10 turns per coil. Its rated speed is 3600 r/min.
Obtain the discrete-time (DT) or sampled signals x[n] = x(nTs) and h[n] = h(nTs) by discretizing the CT signals x(t) and h(t), respectively, using a sampling period of Ts = 0.01 s. This value ensures that the two CT signals can be fully recovered,..
suppose that you wish to offer a voice over ip wireless service. the target packet error rate or drop rate is 103 and
Create and test a function called celsius to convert degrees Celsius to degrees Fahrenheit. The equation for converting temperatures in Celsius to Fahrenheit is T_f=9/5 T_c+32 Display the results as a conversion table for six different temperature..
1. Write this as a Boolean expression in canonical minterm form 2. Rewrite the expression in canonical maxterm form 3. Write the complement of f in 'little m' notation and as a canonical minterm expression
Find the tap coefficients for a three-tap zero forcing equalizer.
A 120-V source is to be connected to a load by two copper wires. The load is located 500 feet from the source. The maximum voltage drop due to the wire resistance is 10 V, which makes the minimum load voltage 110 V.
an astronaut drops an object from rest relative to the planet on a planet alpha having the same radius as of earth
A dc motor has an armature resistance of 0.2Ω and an armature inductance of 5 mH. It is driven by a power converter of gain, kPWM = 100 . Design a controller for the armature current loop such that the crossover frequency is 2 kHz and the steady st..
