X(t) denotes a zero-mean WSS Gaussian random process with power spectral density
1. What is the power in this process?
2. What is the bandwidth of this process?
3. Assuming that this process passes through an ideal lowpass filter with a bandwidth of 50 kHz and the output is denoted by Y(t), determine SY(f), the power spectral density of Y(t), and the total power in the output process.
4. Determine the PDF (probability density function) of the random variable X(0).
5. Find the smallest value of t0 > 0 such that X (0) and X (t0) are independeht.
The circuit has total resistance R. When the magnetic field is perpendicular to the plane of paper is switched on springs are observed to extend further by the same distance, the magnetic field strength is.
A three-phase, 400 V system has the following load connected in delta: between the red and yellow lines, a non-reactive resistor of 100; between the yellow and blue lines, a coil having a reactance of 60 and negligible resistance
Obtain a set of minimum SOP expression for switching circuit that will accept XS3 code at it input and provide BCD code at it output.
An electric bass amp is advertised as being able to deliver 200 Watts toan 8 Ohm speaker and 300 Watts to an 4 Ohm speaker. If the amp is a voltage source with an internal resistance, what is the value of the internal resistance
Assume the mass of the cup and water to be equal to the mass of water alone. Calculate the normal force FN for 300 g and 150 g.
We have v1(t)=10cos(wt+30degrees). The current i1(t) has an rms value of 5A and leads v1(t) by 20s. (The current and the voltage have the same frequency) Draw a phasor diagram showing the phasors.
It is often preferred to use a FET for the RF amplifier in an AM receiver. Can you explain why?
Did the CVPI design meet acceptable engineering standards? Is the fact that the design did not violate federal standards important?
The forces 20N,30N,40N,50N and 60N are acting on one of the angular points of a regular hexagon towards the other five angular points taken in order. Find the magnitude and direction of resultant force
A sample of HCL gas is placed in an electric field of 2-5 x 104 N/C. The dipole moment of each HCL molecule is 3.4 x 10-30 C-m. Find the maximum torque that can act on a molecule.
Based on the data in previous Problem 2.7 and your answers to that problem, determine the average level of work-in-process (number of parts-in-process) in the plant.
Consider the CA3140 op-amp in Figure 13.21. If the bias currents change such that IC5 = IC4 = 300 μA, determine the voltage gains of the input and second stages, and find the overall voltage gain.
