Determine the energy or the power in the signal.
x(t) = e-a*abs(t)
where a > 0 and abs(t) means the absolute value of t.
A point charge of 500π [nC] is located at the origin, an infinite uniform line charge with density of 18π[nC/m] lies along the z axis, and a uniform surface charge density of 2 [nC/m2] lies on all the z = 0 plane.
If the data stream is transmitted using a bandwidth of 64 kHz in an ordinary system (without spread spectrum), what is the SNR that could be tolerated without experiencing significant errors
assuming k>0 what is steady state the response of the above system due to an input of the form , x(t) = 2sigma(t)+u(t). where sigma(t) denotes unit impulse function and u(t) denotes unit step function
A HCS12 ATD is set to 10-bit unsigned mode. The voltage references are set to ground and 1.0V What is the ADT output for a temperature of 81 degrees The temperature sensor measures 0 to 100 degrees with an output of 10 mV/degree.

design a regulated poewr supply with these specs Output a dc voltage of 10 V Load Variation: 0.3 -10000ohms Ripple Factor: less 0.1% for 2000ohms load
Suppose you don't know the probability p of getting a ticket, but you got 5 tickets during the year, and you estimate p by the sample mean p =5/250= 0.02. What is the range of possible values of p assuming that the difference between p and the sam..
A high-voltage transmission line connects a city to the power plant. It consists of two aluminum wires, each with resistance of 4.0 Ohm. The transmission line delivers to the city 1.7x105 kW of power at 2.3x105 V. What is the current in the transm..
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
A telecommunication system has a link bandwidth of 10 MHZ, signal propagation of 3.5 x 10^8 m/s, transmitting as 1500 frames per minute, with 15000 bits per frame, over a distance of 100 km. What is the bandwidth-delay product?
Digitizing an Audio Signal, PAM, ADC, An audio signal has a bandwidth that extends from 100 Hz to 10 kHz. The signal is sampled to create a PAM signal and then digitized by an analog to digital converter (ADC) that has 8 bits.
Consider a hollow spherical conductor with total charge +5e. The outer and inner radii are a and b, respectively. (a) Calculate the charge on the sphere's inner and outer surfaces if a charge of -3e is placed at the center of the sphere.
