Consider the signal shown in Figure 3.15.
1. Find approximation to x(t)
2. Find and plot the magnitude and phase spectra.
3. Find the average power using x(t) directly.
4. Use the Fourier coefficients to find the average power.
What is the magnitude of the internal generated voltage EA at the rated conditions? What is its torque angle d at these conditions?
A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.
Finding voltage across 5 ohms when AC supply is given for the circuit
When the temperature is held constant, the digital display of thermometer A does not change, but the display of thermometer B randomly toggles between three to four adjacent readings (i.e., +/- 2 degrees). For the questions below, assume that the ..
Briefly explain why the maximum usable clock frequency of a ripple counter decreases as moreflip-flops are added to the counter to increase its MOD-number.
FIGURE 4 shows an amplifier circuit. Write a short report on the operation and performance of the circuit. In completing the report you should: Explain the operation of the circuit and in particular the role of resistors R1 and R2.
The cylindrical buoy of diameter 60 cm in Fig. 43 is floating in water with its axis vertical. When depressed downward in the water and released, it vibrates with period 2 sec. What is its weight?
An overflow occurs when the result of adding two number is larger than can be represented. for example, two 4-bit signednumbers will cause an overflow if their result is greater than +7or less than -8.
Assume all that youhave a single 1nF capacitor, any number of op amps,and any numberof resistors. Design a circuit that has a port impedance of1uF.
Design the input and output matching circuits using the given large-signal reflection coefficients. Compute the required input power level.
