Given the image data "cruiseorg.tiff", perform wavelet-based compression by completing the following steps:
a. Convert the image to gray scale.
b. Write a MATLAB program for encoding with the following features: (1) use an 8-tap Daubechies filter; (2) apply the two-level DWT; (3) perform 8-bit quantization for sub bands LL2, LH2, HL2, HH2, LH1, HL1, and HH1 for simulation.
c. Write the MATLAB program for the decoding process.
d. Run the developed MATLAB program to examine the image quality using the following methods:
The voltage between two charged parallel plates is 5 volts (the top plate has more negative potential). What energy is acquired by an electron that is moved from the bottom plate up to the top plate
1. Calculate the total (composite) load power factor, true power, reactive power and apparent power. 2. Also calculate the full-load current and the amount of capacitive KVAR needed to bring the overall power factor to .95 lagging.
Connect the PWM output to an LED, for preliminary testing with slow clock frequency, then to the oscilloscope to show final results with multiple frequencies between 10 KHz to 1MHz. In the final demonstration, connect CLK to CH1, and PWM to CH2
A system has the transfer function: g(s)=7(9) / s(s^2 +(7+9) s + 7(9) a). write this transfer function in polynomial form and pole-zero form.
When played, it produces a sound of 196 Hz. The wavelength of the wave on the guitar string is 1.28 m. A) What is the tension in the string B) If a speaker is using 25 W of power to produce the sound, what is the intensity level measured at a dist..
A particular diode was measured to have VD = 0.62 V at ID = 5.895 mA. Determine the following: a) the reverse saturation current IS. b) VD for a forward current of 100 mA. Assume VT = 25 mV.
Calculate resistance from the measured voltage and current values. Measure the resistance for the resistor in the circuit. Compare the measured resistance to the calculated value of resistance of the resistor.
A separately excited dc motor turns at 1200rpm when the armature is connected to a 115V source. Calculate the armature voltage required so that the motor runs at 1500rpm.
Assuming that your mother is not an electrical engineer or computerengineer, briefly tell how you would explain to her the difference between a RISC machine and a CISC machine and how you would explainthe advantage and disadvantages of each approa..
Consider a 4-bit unipolar binary-weighted D/A converter with v(1)= 1 V, V(0) = 0 V, and Rf= 8R. Obtain the analog output voltage for each of the digital inputs from 0000 to 1111
For the three transistor configurations namely, the common-eitter, the common-collector, and the common-base, compare the voltage gain and the current gain for each configuration.
A series-connected load draws a current i(t)=4cos(100pt + 10°) A when the applied voltage is v(t) = 120cos(100pt-20°) V. Determine a) The circuit‘s apparent power b) The power factor, pf c) The value of the impedance Z
