An Amplifier has an input voltage of 10mV rms and an output voltageof 5V rms across a 10-Ω load. The input current is 1μArms. Assume that the input and output impedances are purelyresistive. Find the input resistance. Find the voltage gain,current gain, and power gain as ratios and in decibels.
The sun is at an altitude of 30 degrees to the horizontal. What is the corresponding air mass What is the physical significance of air mass Mars has a very thin atmosphere containing primarily CO_2 and dust particles.
A digital output voltmeter has an input range of 0 to 30 V and displays three significant figures XX.X. The manufacturer claims an accuracy of ±2% of full scale. With a voltage reading of 5 V, what are the percent uncertainties of the reading due ..
implement the following boolean function F, using two-level forms (a)NAND-AND, (b)AND-NOR,(c)OR-NAND,and(d)NOR-OR: F(A,B,C,D) = Σ(0,1,2,3,4,8,9,12)
A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load.
A plane waveis obliquely incident on a perfectly conducting half-space. The magnetic field is perpendicular to the plane ofincidence. The incident Ehas anamplitude of 1V/m,and the incident angle is θi.
For both designs, the supply voltage is nominally 9 V and varies by +/- 1V. For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA. For the second design, assume that the current f..
An initially charged capacitance discharges through a resistance. At one time constant, what percentage of the initial voltage reamins What percentage of the initial stored energy remains
Assume A is the MSB and B is the LSB. The circuit produces an output of 1 if and only if the sum of the current 2-bit input and the previous 2-bit input is equal to 6. Design the circuit using as few D flip flops as possible. Draw the state diagra..
a 60 Hz power generator is in series with a 800 Ohm resistor and 4 micro farad capacitor. Calculate the power concert.
Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
Identify the types of system-building methods used by Dorfman to build its wireless warehouse system.
Consider the function f which has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Write the canonical product-of-sums expression for f. Do not use the shorthand notation
