A circuit to compare two 4-bit numbers (A3-0 and B3-0) is to be designed. The status of the comparison is available on the outputs Equal, Not_equal, Less_than, and Greater_than. Write the entity of the circuit.
Find the transfer function and the difference equation for a 2nd -order FIR filter that has unity d.c. gain, but for which the given input x(k) produces zero forced response. (Your filter will have a "notch" at the given frequency, and H(1) =1.)
Assume that you have a diff amp circuit with a tail resistor. You have determined that the CMRR of the circuit is not acceptable. How could you improve the CMRR?
It is estimated that youw ill pay about $80,000 into the social security system over your 40-year work span. For simplicity, assume this is an annuity of $2,000 per year, starting with your 26th birthday and continuing through your 65th birthday.
A single phase full bridge inverter feds power at 50Hz to RLC load with r=5 ohms , l=0.3H and C=50μF. The dc input voltage is 220volts. (a) Find an expression for load current up to fifth harmonic
As current passes through the wires, the wires heat up, thus toasting the toast. Estimate the overall resistance of a heating element which is 220 cm long and consists of nichrome wire with a diameter of 0.56 mm.
A dynamite blast at a quarry launches a rock straight upward, and 1.6 s later it is rising at a rate of 14 m/s. Assuming air resistance has no effect on the rock, calculate its speed (a) at launch and (b) 5.7 s after launch.
What is the attenuation per octave between 1 kHz and 10 kHz? What is the increase in attenuation between 5 kHz and 10 kHz?
The dc supply voltage is VT = 200 V, the armature resistance is RA = 0.085 Ω, the field resistance is RF = 10 Ω, and the adjustable resistance is Radj = 2.5 Ω. At a speed of 1200 rpm, the rotational loss is Prot = 1000 W.
Find the impulse response sequence y(n) due to the impulse sequence δ(n);
In a certain n-type region of a semiconductor in thermal equilibrium, there is a hole concentration with the following spatial distribution: po(x)=103(1 9×103x)cm 3 for0 x 10 4 withxincm Assume that in this region, the electron mobility and hole mob..
A turn contains three blue and seven white chips. A chip is selected at random. If the color of the chip selected is white, it is eplaced and two more white chips are added to the urn.
The effective water head for a 100 MW station is 220 metres. The station supplies full loadfor 12 hours a day. If the overall efficiency of the station is 86.4%,find the volume of water used.
