An accelerating voltage of 2.45 *10^3 V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 35.3 cm away.(a) What is the magnitude of the deflection on the screen caused by the Earth's gravitational field?(c) What is the magnitude of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 µT down?
1. Two resistors R1 = 5.6 kΩ and R2 = 3.3 kΩ are to be connected in series. Calculate the series equivalent resistance Rs. 2. The same two resistors are reconnected in parallel. Calculate the parallel equivalent resistance Rp.
A 3.5inch floppy disc has a nominal capacity of 2 MB. Note that there are eight bits to a byte. Estimate the area of magnetic material allocated to each bit of information. Clearly state any assumption made and carefully note any measured quantiti..
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal)
the upper critical frequency of anop-amps open loop response is 200Hz. If the midrange gain is 175,00, what is the ideal gain at 200Hz? what is th actual gain? what is the op-amps open loop bandwidth?
Suppose we had connected at the input to channel 0 a circuit of the type that attenuates all frequencies above 50 Hz at a rate of 6 dB/octave. What will we then see in the output when we apply 4960 Hz at the input
Design a circuit to give uninterrupted 5 V dc power supply with 110 V 60 Hz line voltage as input. The dc output should be available in case of power outage (110 V line supply). In case of line failure, the circuit should switch to backup source t..
A three-point symmetric moving average filter, referred to as a weighted moving average is of the form \(y[n]=b(ax[nu22121]+x[n]+ax[n+1])\) (a) Determine as a function of a and b the frequency response \(H(e^{j\omega})\) of this system.
describe the steps in the procedure based on grid-based color/texture histogram similarity measure for database retrieval of images that closely match a query image.
Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0
Write the VHDL assignment operator for the Y1 output of a BCD-to-binary encoder. Use Boolean operators, D0-D9 as the data inputs lines and Y0-Y2 for the outputs. Inputs and outputs are active-HIGH.
If the balloon has a diameter of 12 m and carries two people, 85 Kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is p= 1.16 kg/m^3, and neglect the weight of the ropes and the cage.
A DSP system has a sampling frequency of 800 HZ. What is the maximum frequency of the analog signal so that the aliasing would not occur
