Sketch a Bode plot for the frequency response of a High-pass R-C filter where R=470ohms and C=0.047uF. Draw the circuit, calculate the actual cutoff frequency, and calculate the dB level at one-half the critical frequency and twice the critical frequency.
What are the exact form of the equations for the 2nd-order step response for the underdamped, critically-damped, and overdamped conditions.
A 300-km bundled 500-kV, 60-Hz, three-phase completely transposed overhead line has three ACSR 1351-kcmil conductors per bundle, with the bundle spacing 0.5 m. The horizontal phase spacings between bundle centers are 10, 10, and 20 m.
Determine the current drawn from a three-phase 440 V line by a three-phase 15-hp motor operating at full load, 90% efficiency, and 80% power-factor lagging. Find the values of P and Q drawn from the line. (Hint: 1hp = 746W)
A sequential circuit with three D-type flip-flops Y1Y2Y3, input X and output Z is defined with the following input/output functions: D 1 = X Y 3 + X Y 1 Y 3 D 2 = X ( Y 3 + Y 2 ) + X Y 2 Y 3 D 3 = X Y 3 + Y 2 Y 3 Z = Y3
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
A single-turn resonant circular loop with a /8 radius is made of copper wire with a wire radius of 10^4 pi f/2 and conductivity of 5.7 × 10^7S/m. For a frequency of 100 MHz, determine, assuming uniform current
The total sunlight at noon on a clear summer day is just over 1KW/m^2. Assuming a solar panel with 20% efficiency, and an output voltage of 20V, estimate the output current of a one square meter panel in full sunlight.
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
An abrupt p-n junction has a doping concentration of 1015, 1016, or 1017 cm-3 on the lightly doped n-side and of 1019 cm-3 on the heavily doped p-side. Obtain series of curves of 1/C2 versus V, where V ranges from -4 to 0V in steps of 0.5V.
Solar Cell Consider a GaAs PN junction solar cell with the following parameters. Na=10^17 cm^-3, Nd= 2*10^16 cm^-3, Dn=190 cm^2/s, Dp=10 cm^2/s, Tn0=10^-7s, and Tp0=10^-8s.
Single pole amp. has an open loop gain 10^6 and open loop bandwidth of 10Hz. If the feedback factor =1, calculate the gain and bandwidth after the feedback
a. The mass of an electric car is 900 kg including the passengers. A single motor mounted on the front wheels drives the car, and the radius of the wheel is 0.3 m. The car is going downhill at a speed of 50 km/hr, and the slope of the hill is 30 d..
