A panasonic model Rx-ft560 stero uses a 12V_dc powwer supply. At full volume ( max triple min-bass) A max current of 1.4 amps is needed from the power supply. at min volume, this drops to 200mA. (hint: calculate the range of R_L)
Design a full wave rectifir power supply using a 9.52:1 transformer. Assume that the outlet is 120V_rms at 60Hz further assume that the diode drop, V_d(on) is 1v
pick the value of C_L such that V_o has a maximum ripple of 1 Vp_p
Solve for the average value of V_o = V_o
(this may be greater than 12v) and I_d(avg)= I_d
B) Add a series resistor to the secondary to limit the maximum source current to 10 amp if the secondary winding resistance is 0.4 ohms .
A 9.2 kg crate is pulled up an incline with initial speed of 1.2 m/s A pulling force of 105N is applied parallel to surface of incline which is at angle of 21.8 degrees to horizontal The coefficient of kinetic friction is .32 and crate is pulled d..
What are the positive and negative implications of wireless energy?
Find the impulse response fpr the filter? How many nonzero terms does the impulse response contain?
Whether reading consecutive 20 bits from the same wordline would consume about 20 times more energy than reading 1 bit from this wordline. What is the total storage capacity of this DRAM array
A silicon (ni= 10^10 cm^-3) p-n junction diode has a maximum electric field of -10^6 V/cm and a depletion layer width of 1 um. The acceptor density in the p-type region is four times larger than the donor density in the n-type region.
by finding the relevant air analysis, determine the partial pressure of nitrogen in the athmosphere at 1.00bar.f a sample of air at this pressure and 10°C was put nto a rigid container and then itd temperature raised to 91°C, what would be the pre..
The river estuary is tidal causing the surface level of the water to rise and fall. At certain times of day, reflections from the water surface cause deep fading of the received signal.
the frequency response h(e^jw) of a length-4 finite impulse response filter with a real impulse response h[n] that the following specific value: h(e^j0)=13, H(e^j3pi/2)=-3-j4, and h(e^jpi)=-3. determine the 4th discrete fourier transform (DFT) of ..
A controlled three-phase six-pulse AC/DC converter is supplied with 60 Hz voltage of the line-to-ground RMS value U = 240 V with the output current ideally filtered by an inductor. The maximum DC power of the converter (Pd)max = 50 kW.
Construct a truth table for the following specifications: if any two consecutive switches out of four on-off switches in a row are on, then a light is on; otherwise, the light is off. Denote the switches in order as a, b, c, d,
If the application program creates a message of 150 bytes and each layer (including the fifth and the first) adds a header of 20 bytes to the data unit, what is the efficiency (the ratio of application layer bytes to the number of bytes transmitte..
A dc separately excited generator runs at 1200 rpm. the rated current and voltages are 100 A at 240 V. The armature resistance is 0.15 (ohms). The open circuit magnetization characteristics at 1200 rpm are
