Unpolarized light of intesity Io is incident on a polarizer-analyzer pair. If the angle between the polarizer and analyzer is 26°, what light intensity is transmitted through the polarizer and analyzer respectively? Your answers will be in terms of Io. Use 3 significant digits.
Derive the PLA programming table for the combinational circuit that squares a three-bit number. Minimize the number of product term.
Consider a permanent-magnet dc motor with the following parameters: Ra=0.35Ω, La=1.5 mH, Ke=0.5 V/(rads/s), Kt= 0.5 Nm/A, and Jm= 0.02 Kg.M^2. The rated torque of this motor is 4Nm.
What are advantages and disadvantages of using digital circuits in lieu of analog circuits to measure different parameters in mechanical systems
For input signal voltages between these limits, the input should pass unaltered to the output. The peak current drawn from the input source may not exceed 1mA. You may use any circuit component we've studied except opamps.
Design a load resistor (resistance rating and power rating) network to have the transformer operate at full load. Design a second network for half load. You may need to combine several resistors to get the desired value.
Because A-B=A+(-B), the subtraction of signed numbers can be accomplished by adding the complement. Subtract each of the following pairs of 5-bit binary numbers by adding the complement of the subtrahend to the minuend.
A 15hp (output power), 208V, three phase, six pole, y-connected induction motor has the following parameters: R1 = 0.1 ohm R'2= 0.1 ohm Xeq = 0.5 ohm A.) A fan type load is connected to the motor. The slip of the motor in this case is 2%.
A torque of 18 N-m is applied to a rotating part. The moment of inertia is 0.078 kg-m2. How much time (in seconds) will it take to rotate the part 180°?
Design a frequency divider cicuit that will produce the following three ouput signal frequencies: 1 MHz. 800 kHz, and 100 kHz. Use 74HC160 and 74HC161 counter chips and any necessary gates. The input frequency is 12 MHz.
A system is required that represents 0 to 100 volts in a 10 bit code. What is the voltage increment that is represented by the LSB of this code.
you have a bandwidth of 10 mhz per direction in a single-cell system and want to deploy a wireless telephone system.
An amplifier operating from a single 15-V supply provides a 12-V peak to peak sine wave signal to a 1-k ohm load and draws negligible input current from the signal source. The dc current drawn from the 15-V supply is 8mA.
