a) Using K-Map, find the minimum product-of-sums for the following function. Circle the term on the map and write the result in algebraic form.
b) Draw the block diagram in NOR-NOR.
f(a,b,c,d)=m(0,1,2,3,5,9,11,13)+d(6,10)
A transformer is used to match an 8 ohm speaker to a 500ohm audio line. What is the turns ratio of the transformer what is the input voltage and output voltage when 15W is being delivered to the speaker
Use MATLAB to compute the inverse Laplace transform of X(s)=(s^2+2s+1)/(s(s+1)(s^2+10s+50)) and determine the value of x(t) in the steady state. How would you be able to obtain this value without computing the inverse? Explain.
A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate a) The line-to-neutral voltage per phase.
The location of the zeroes in the spectrum suddenly changes to 5 kHz, 10 kHz, 15 kHz.... What parameter of the rectangular pulses has changed and what is its new value?
A 150 MVA, 24 kV, 123% three-phase synchronous generator operates with an induced voltage that is twice the rated line-to-neutral voltage. Calculate the three-phase steady-state short-circuit current at the generator terminals.
What is the motor efficiency as operated?
a 9.1 v zener diode exhibits its nominal voltage at a test current of 28 mA . at this current the incremental resistance is specified as 5 ohms . find Vz0 of the zener model . find the zener voltage at a current of 10 mA and at 100 mA.
What is the effective data rate of this transfer (not counting the time for reading or writing the DVDs)?
A line has an inductance of1.25mH/km with an impedance angle of 70 degree , and a capacitance to neutral of 0.01mF/km. Calculate its reactance and series impedance per unit length at 50Hz. Calculate the line admittance per unit length
The op-amp circuit measures the changes of temperature in a system. The output voltage is given by v0(t) = -R(t)vi(t). Suppose that the temperature in the system changes cyclically after t = 0, so that R(t) = [1 +0.5 cos(20πt)] u(t) and let the in..
What is the minimum number of bits required to represent each of the following decimal numbers: 10, 1000, 100,000, and 1,000,000?
