A capacitor consists of two concentric long cylindrical conductors of radii a and c, where c > a, and each is of negligible thickness.
The space between the conductors is filled with two layers of dielectric materials. Using cylindrical co-ordinates with z-axis along the axis of the cylindrical conductors, the space is filled with an LIH (linear, isotropic and homogeneous) dielectric of relative permittivity and the space with a second LIH dielectric of relative permittivity . The cylinders are sufficiently long that end effects can be neglected. The charge per unit length of the inner conducting cylinder is , and that on the outer conducting cylinder is .
a) Use the integral version of Gauss's law to find the electric field E and the electric displacement D in the region . Hence calculate the electrostatic field energy stored in a length l of the capacitor.
b) Hence find the capacitance of a length l of the capacitor.
A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.Write equation for modulated signal What is average transmitted power & modulation index
Design a synchronous counter with the following repeated sequence:2-4-6-1-3-5. Build the counter with T flip-flops and minimized gates. Assume the (active low)asynchronous clear is tied to a logic 1.
A room is heated by a baseboard resistance heater. When the heat losses from the room on a winter day amount to 6500 kJ/h, the air temperature in the room remains constant even though the heater operates continuously. Determine the power rating of..
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference. At 200°C a type K TC produces 8.13 m..
Clearcly, any noise will pass straight through to the ADC subsystem, introducing measurement error. You have two choices to mitigate this: SW filtering and HW filtering. Assume the uC sample rate, Fs, is 100 Hz with 8 bit resolution.
a) Find the sample mean. b)If the calculator produces three digit random numbers that are uniformly distributed between 0.000 and 0.999, find the variance of the sample mean.
a) Using 10 nF capacitors and ideal op amps, PROBLEM design a high-pass unity-gain Butterworth filter with a cutoff frequency of 2 kHz and a gain of no more than -48 dB at 500 Hz. b) Draw a circuit diagram of the filter and label all component valu..
If one of the resistors in a parallel circuit were shorted, what would you expect to see happen and could a shorted component in a parallel circuit cause an open to occur elsewhere.
Using this method, create and test a minority vote circuit, a circuit designed to indicate when one or no inputs are HIGH. Determine the appropriate SOP equations, enter, compile, simulate, download, and test your solution.
Design a simple circuit diagram,to complete the following task.1)Green lamp light up when the system is ON. 2)Once the pushbutton is pressed, Green Lamp turns OFF and Red Lamp turns ON,Motor starts to spin.3) Once the sensor detect the motor rotat..
