Let x(t) = |cos120pit| a periodic signal. Plot x(t). What is the period and frequency of x(t)? Expand x(t) in trigonometric Fourier series Hint: use the plot to find the Fourier coefficients.
1)Why BJT is called a bipolar and current controlled device 2)What are the different modes of operation in BJT and in which region it act as an amplifier 3)Why Emitter is highly doped ,base lightly doped and collector moderately doped
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
Assume all your standard value resistors are accurate to 0.1%. What would be the worst-case variation in overall resistance for your design (both high and low). How might you construct a resistive network using the smallest number of standard resis..
Question about Complex power, If an electrical load operates at 240 Vrms.The load absorbs an average power of 8kW with .8 lagging power factor
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
A three-phase, eight-pole, 60 Hz synchronous generator has a 60 mWb flux per pole. The winding is full-pitched, and the distribution factor is 0.96. The armature has 120 turns per phase. Calculate the induced voltage per phase.
The 8086 Microprocessor Operating Systems and System Interrupt services, Please help me write a program that will display the hex code for any key, or key combination, that is pressed on the keyboard.
An a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at a frequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental, a 5th harmonic which is 10% of the fundamental and at a phase angle of 1.2
Assume that your application has 600 data reads for each 4000 instructions. For the same number of instruction the application has 400 data writes. The cache used has an instruction miss rate of 0.6% and a data cache miss rate of 6%.
explain the function of frequency dial and frequency range.
The noise voltage in an electric circuit can be modeled as a Gaussian random variable with 0 mean and 10^-4 standard deviation. This noise passes through a half wave rectifier with the characteristics g(x) = { x, x>0 and 0, x
