Determine if the following CT signal is periodic. If yes, calculate the fundamental period T0 for the CT signal:
x(t) = 2cos(4*pi*t/5)*sin^2(16t/3)
A conducting sphere in free space has a radius of a= 10cm. the capacitance of the isolated sphere is C= 4oa. now let's coat the sphere with a dielectric with fr= 3, and the thickness of the dielectric layer is d.
The practical voltage source is formed by combining an ideal voltage source (Vs) and internal resistance (r). 1) Without computing, determine sign of power Ps delivered by voltage source
resistor: a volt-ohmmeter with an internal impedance of 1000 Ω/V and an EVM with an impedance of 11 MΩ. Calculate the voltage indicated by each of these devices.
A signal x(t) can be represented as x(t)=xe(t)+xo(t) where xe(t)=(1/2){x(t)+x(-t)} is the even part, and xo(t)=(1/2){x(t)-x(-t)} is the odd part of the signal. Let x(t) be an energy signal with an energy of 20 Joules. Suppose the even part of x(t) is..
A 78oham lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75oham
A sled is traveling at 4 m/s along a horizontal stretch of snow. The coefficient of kinetic friction is 0.05 . How far does the sled go before stopping ?
Two random variables X and Y have a joint probability density function given by f(x,y) =kxy 0
You do some quick measurements and find that the area of the lagoon behind the dam would be about 5m wide by 20m long, and the lagoon would be about 3m deep at high tide, and 1m deep at low tide.
(Probability of negative lifetime is negligible) Lifetime of chip 2 is also a Gaussian RV with mean 22,000 and standard deviation 1000 hours. Which is preferred if the target lifetime of the system is (i) 20,000 hours and (ii) 24,000 hours
Explain the following terms; (i) critical radius of insulation. (ii) economic lagging thickness.
A half wave dipole antenna is operating in air at a frequency of 100 MHz. At a distance of 1000 km and at an observation point ? = ?/2, electric field strength is measured to be 5 µV/m. Calculate the a. Length of the antenna
For input signal voltages between these limits, the input should pass unaltered to the output. The peak current drawn from the input source may not exceed 1mA. You may use any circuit component we've studied except opamps.
