A d-c voltage Vo is applied att = 0 directly to the input terminals of a lossless air dielectric transmission line of length l. The line has a characteristice resistance Ro and is terminated in a load resistanceRL =2Ro.a) Draw the voltage and current reflection diagrams.b) Sketch V(l, t) and I(l,t).c)Sketch V(z,2.5T) and I(z,2.5T)
An engineer makes an accurate flux plot for a pair of linecharges. one line charge has a fixed ?=1.00[C/m] and islocated on the x axis at x=-h. The other line charge has f=-0.75[C/m] and is located on the x axis at x=h.
Suppose 33 mL of 1.20 MHCl is added to 42 mL of a solution containing excess sodium hydroxide, NaOH, in a coffee-cup calorimeter. The solution temperature, originally 25.0C, rises to 31.8C.
1) Determine the number of possible PCM values that can be encoded for (a) 6 bits and (b) 10 bits. 2)it is desired to represent an analog signal in no less than 500 values. determine the minimum numbber of bits required for each word.
A photocell with a 35-ms time constant is used to measure light flashes. How long after a sudden dark-to-light flash before the cell output is 80% of the final level
Using the IIR digital filter design, determine the difference equation to generate a single 852 Hz tone with a sampling frequency of 8000Hz
An AM signal is written as xc(t) = Ac (1+ µx(t))cos(2pi*fc*t) where fc is the carrier frequency, Ac is the carrier amplitude, µ is the modulation index, and x(t) is the baseband message signal. We assume that x(t) has absolute bandwidth W
Determine whether the following signals are periodic. If they are, find the smallest periods (fundamental periods). a) f(x,y) = sin (2 pi x) cos(4 pi y) b) Discrete signal: f(m,n) = sin ( pi * m / 5) cos(pi * n / 5)
1.5- kW toaster takes roughly 3.5 minutes to heat four slices of bread. Find the cost of operating the toaster once per day for 1 month ( 30 days). Assume energy costs 8.2 cents/ kWh.
A tank circuit coil is operating at a resonance frequency fres = 20 MHz; The circuit must operate with a bandwidth of 200 kHz. What is quality factor, Q, for the coil
An electric dipole has opposite charges of 5.0x10^-15 C separated by a distance of .40mm. It is oriented at 60 degrees with respect to a uniform electric field of magnitude 2.0x10^3 N/C. Determine the magnitude of the torque exerted on the dipole ..
A system has the following input/output relation: y(n) = x(n) + .5 y(n -1). If the input x(n) is the sinusoidal signal shown in problem 1.32(d) (Above), the steady-state output will have the following form: y(n) = A sin(Bn+C). Determine the value ..
