1. A bandpass filter has lower and upper cutoff frequencies of 445 and 7800 Hz, respectively. What are the bandwidth, center frequency, and Q? Is this a wideband or narrowband filter?
2. If a bandpass filter has cutoff frequencies of 20 and 22.5 kHz, what are the bandwidth, center frequency, and Q? Is this a wideband or narrowband filter?
An asphalt plant will produce 180 tph for a highway project. - If it is desired to keep the rolling speed under 3 mph, how many rollers are required for the project?
a) Calculate the distance the ball hits the ground from the goal line b) Calculate the quarter back's distance from the goal line when the ball hits the ground
Find the Thevenin and Norton equivalent circuits for the circuit. Find the maximum power that this circuit can deliver to a load if the load can have any complex impedance. Repeat if the load must be purely resistive.
A DC voltage of 10 V is applied across a parallel platecapacitor with a 2 cm separation between the plates. Knowing that the potential field distribution inside the capacitor is linear, plot the potential and electric fields inside the capacitor.
Which components in an analog filter determine its frequency-dependent behaviour and how can this be described?
A circuit is needed to divide a 10 Hz signal down to 1 Hz. using only a 7493 4 bit counter produce a logig diagram for both designs , hook the clock input to a 10 Hz clock on the logic designer and hook the output clock to an LED.
A random signal X can be observed only in the presence of independent addictive noise N. The observed quantity is Y = X + N.The joint probability density function of X and Y is f(x,y) = K exp[-(x2 + y2 + 4xy)] all x and y
F = B'D' + A'B'C + ABC + CD' Draw a circuit for this function using only AND , OR, and NOT gates. The function calls for two 3-input AND gates and one 4-input OR gate. All you have available, however, are 2-input AND and OR gates
A wave traveling in a lossless, nonmagnetic medium has an electric field amplitude of 24.56 V/m and an average power density of 2.4 W/m2. Determine the phase velocity of the wave.
The terminal voltage of the battery is v=11 +0.5t for t>0. a. Find the energy delivered to the battery during the five hours. b. If electrical energy costs 10 cents/k Wh, find the cost ofcharging the battery for five hours.
