Two Random variables have a joint probability distribution function defined by F(x,y)=0 X<0,y<0 =xy 0<(=)x<(=)1,0<(=) y<1 =1 x>1y>1 A). Sketch this distribution function. B). Find the joint probability density function and sketch it. C). Find the joint probability of the event X1/4
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
A 277/480V three phase wye system has the following load: M1- Induction Motor, 50hp, n=0.91, PF= 0.89 at full load. M2- Induction motor, 25hp, n=0.9, PF= 0.9 at full load. R- Heater Load, PF=1 M- A synchronous motor to drive a second 25hp load.
the total amount of electricity that could potentially be generated from wind in the U S has been estimated at 10.8*10^9 Mw-hr annually , if one tenth of this potential is developed, estimate the number of 2 Mw windmills
A sinusoidal voltage with a peak-to-peak value of 15 v is applied to an RC high-pass filter. If the reactance at the input frquency is zero
The tuning control is required to provide a uniform, linear change in frequency for a fixed rotation of the knob, e.g., 25 kHz per revolution at any operating frequency. You are considering three options for controlling the frequency
A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load
What are the four characteristic parameters of transmission line? Which parameter is used to calculate the real loss? Which parameter is used to calculate the charging current? Which parameter is almost negligible and why?
how do we determine the direction of current in a multiloop circuit with more than one source of e.m.f?
what is the minimum coefficient of friction that will prevent sliding.
What is the PIV required of the diode? A half-wave rectifier employing a 12-V-rms 60-Hz sine-wave source and no dc load is filtered using a polarized electrolytic capacitor having a small leakage current.
A certain lightbulb has a tungsten filament with a resistance of 21.9 when at 20.0°C and 145 when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here.
