Consider a unity-feedback control system with the following open-loop transfer function:
Draw a Nyquist plot of G(s) and examine the stability of the closed-loop system.
Suppose a car is traveling at +23.2 m/s, and the driver sees a traffic light turn red. After 0.563 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 7.00 m/s2. What is the stopping distance of the car
1.) (a) What is the difference between the sign-magnitude and 2's-complement systems of representing signed binary numbers. (b) What is the advantage of using the 2's-complement system to represent signed numbers.
There are approximately 109 million TVs in the United States. Each uses, on average, 79 W of power and is turned on for 6.9 hours a day. If electrical energy costs 0.073 dollars per kWh, how much money is spent every day in keeping the TVs turned ..
Measurements show that for a particular arrangement of the equipment and at a particular amplifier setting, the system will howl if 1% of the output power is fed back to the microphone. Estimate the power gain of the P.A. amplifier in decibels.
Selecting a manufaturer from the us and observing wether its annual revenues are more than one billion or not when it is known that 30% of all manufacturers have annual revenues totaling more than one billion dollars.
an electron experiences a magnetic force with a magnitude of 4.40times10-15 n when moving at an angle of 56.0circ
For arrangements F and G find the expression for the electric field at the position of the test charge due to the two fixed charges
An electron moving in the positive x-direction perpendicular toa magnetic field experiences a deflection in the negative z-direction. What is the direction of the magnetic field
The current amplification factor β of a BJT is very sensitive to the base width as well as to the ratio of the base doping to the emitter doping. Calculate and plot β for a p-n-p BJT with Lnp = Lpn for: (a) nn = pp and Wb/Lnp = 0.01 to 1
Design a 2nd,4th , and 6th order Butterworth band stop filters with a center frequency at 450 rad/sec and a bandwidth of 100 rad/sec. the final answer should be a ratio of polynomials in descending power of s.
Design a DC motor control system to run the 48V DC motor at 40rpm up to max load of the motor
Choose the best answer for what a DC blocking or coupling capacitor does, assume the capacitor value is chosen to be too small. Blocks the DC and is relatively high impedance to the AC voltage. Blocks only the AC voltage going ..
