Consider a stereo speaker enclousure containing two speakers- a "woofer" to handle low frequency sounds and a "tweeter" to handle the high frequency ones as shown below.
A) The woofer can be modeled as a series R-L low pass filter. Suppose that a given woofer has an inductance of 750 micron Hertz and a resistance of 4 Ohms. At what frequncy (in Hertz) does its frequncy response drop by 3dB ?
B) To prevent the tweeter from accepting too much current at low frequencies and distorting the overall sound, speaker designers employ a capacitor placed in series with the tweeter, as shown in the figure. This is called a "Crossover circuit" since the idea is to set the 3dB frequncy of the tweeter to match the 3dB frequncy of the woofer (I.e. the Bode plots "crossover" each other.) Suppose that the tweeter behaves like an 8 Ohm resistor; what value of C will set the 3 dB frequency of the tweeter to the value from part(a)?
A computer employs RAM chips of 256 x 8and ROM chips of 1024 x 8. The computer system needs 2K bytes of RAM, 4K bytes of ROM, and four interface units, each with four registers. A memory-mapped I/0 configuration is used.
write a script that will call: a function to prompt the user for an angle in degrees and call a function to calculate and return the angle in radians (note:pi radian =180) and call a function to print the result.
We represent this by a non-overlapping sequence detector. In other words, asa soon as you detect the sequence, you will need to get another complete sequence to unlock. Therefore, you need to carefully choose to which state you will need to go.
draw out a schematic that implements a 3-bit XOR gate, but consisting of only 2-bit NAND gates. Your schematic should have from 8-10 NAND gates, but NO other logic function such as OR, AND, INV gates can be in your final design.
The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3185 kJ/kg at the exit of the high-pressure turbine, and 2247 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, determine the w..
The counter will use the falling edge of the clock (denoted by Clk) and have a separte reset pin (R) which will reset the counnter to 0000 when it is low (e.g. R=0). Please use D type flip-flops. write down the state diagram , and state table.
Discuss the trade-offs between fiber optic and satellite communication in terms of costs, signal capacity, signaling method, interference, likelihood of failure and repair issues, multipoint capability, reconfiguration capability, and noise.
1- A particular gas exerts a pressure of 2.79 bar. What is this pressure in units of pascals 2- A particular gas exerts a pressure of 3.43 bar. What is this pressure in units of atmospheres 3- A particular gas exerts a pressure of 4.79 atm.
Suppose you are working for an aircraft company on a positioning control system that controls the position of the landing for their aircraft. This positioning system requires a feedback signal from a position sensor.
On Earth, we assume normal room temperature is 293 degrees Kelvin. From this, we find that the power spectral density of thermal noise is -174 dBm/Hz. On Venus, the average surface temperature is 462 degrees Celcius.
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
