explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the precise mathematical definitions; a simple explaination in plain english will do).
R1=1k ohms, R2=1.5k ohms and R3=3k ohms. Assume an ideal opAmp. Indicate the PEAK current in each of the resistors.
A balanced three-phase inductive load is supplied in steady state by a balanced three-phase voltage source with a phase voltage of 120 V rms. The load draws a total of 10 kW at a power factor of 0.85. Calculate the rms value of the phase currents
determine the equivalent impedance of the transformer referred to the high side (assume the equivalent resistance is negligible). Hint: draw a phasor diagram showing I E V and the impedance drop.
The MFSK scheme is used in conjunction with an FHSS scheme that hops among 4 different carrier frequencies. What is the number of possible frequency assignments. List the possible frequency assignments.
Design the combinational 3 bit gray to binary code converter for conversion angular position of a shaft into binary code. 1) Complete the truth table 2)obtain the minimal solution with a K map 3) draw the circuit diagram, labels the inputs and output..
A 1000V, 50 hp compound motor runs at a speed of 750 rpm at full load. The armature, series and shunt field resistances are 0.5 ohm, 1 ohm, and 200 ohm, respectively. The motor efficiency at this condition is 80%. Calculate the motors starting cur..
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
A binary waveform of 53000 bits/sec is converted into an 8192 level waveform that is passed through a channel with a raised cosine-rolloff filter characteristic with r = 0.33. The channel bandwidth is what
The global radiation at the solar noon on a summer solstice in Albuquerque, New Mexico (latitude 35° N) is 60mw/cm^2. Assume that (a) 30 % of this irradiance is diffuse radiation and (b) the ground surrounding a PV module is non-reflecting
Air is to be compressed from atmospheric pressure at 60oF to 100 psia in a centrfugal compressor (isentropic efficiency about 0.7). The flow rate will be 500 lbm/min. Specify the horsepower required for the driving motor
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Come up with (draw) a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
One reason that the maximum electric field is important is because of the possibility of impact ionization, which may be desired or undesired in a particular application. The process of impact ionization is dependent on the electric field
