1. Describe the relationship between peak current, peak-to-peak current, and rms current. Include in the discussion which values can be demonstrated with the laboratory test equipment.
2. Describe the operation of the series RC circuit. The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drops across the resistor and the capacitor at very low and very high frequency values.
3. Describe the characteristics of the series RC filter circuit with the output across the resistive component. Distinguish the pass and stop bands with reference to the cutoff frequency. Also, state what happens to the circuit complex impedance at the cutoff frequency.
design a 4th order Butterworth band-pass filter, using a low-pass filter followed by a high-pass filter, to extract the 1200Hz and 1500Hz components from the signal x(t) a. Determine the cut-off frequencies of the low-pass and the high-pass filters..
Current Pulses over a Twisted Pair Telephone Line, A twisted pair telephone line has a constant attenuation between 0 Hz and 3300 Hz and linear phase shift with frequency
an adiabatic throttling process for R-134a takes saturated liquid at 800 kPa entering, and drops the pressure to 280 kPa (constant specific enthalpy). Determine the quality exiting and the specific entropy change for the throttling process.
A composite analog signal is given in the following expression: x(t)=1.2 sin(2pi60ft)+0.0001cos(2pi1ft) -If this signal was sampled at 1000 Hz, derive the expression for the sampled sequence x[n] with n being the sampling index.
A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.
A thin spherical shell of 0.4 kg and a diameter of 0.2 m is filled with alcohol of density 800 kg/m^3. It is released from rest at the bottom of a container of water. Calculate the acceleration of the shell as it rises to the surface.
Using coppers resistivity of 10.30 CM-olm/ft at +25 °C, find how long a 1 inch square bar of copper would need be to have a resistance of 1 at +20 °C
An electric field of 3.10×105 is desired between two parallel plates, each of area 36.0 and separated by 0.620 of air.What charge must be on each plate?
An initially charged capacitance discharges through a resistance. At one time constant, what percentage of the initial voltage reamins What percentage of the initial stored energy remains
You have a shortwave AM receiver (just an AM receiver that has the capability to receive signals in the FM frequency band) that receives an NBFM voice signal at some carrier frequency. You notice, however, that while the signal strength is maximiz..
A wire carrying a current is shaped in the form of a circular loop of radius 4.0 mm. If the magnetic field strength at its center is 1.1 mT with no external magnetic fields contributing to it, what is the magnitude of the current that flows throug..
