Using Multisim, design a system using the photoconductive cell shown in the figure below to measure and display light intensity. Make the design such that 20 to 100mW/cm2 produces an output of 0.2 to 1.0V. What is the readout error when the intensity is 60mW/cm2? Show all calculations and Multisim results.
or the turbidity system show in Figure 2 below, two matched photoconductive cells are used in R vs. IL as given in Figure 3 below. Design a signal-conditioning system that outputs the deviation of the flowing system turbidity in volts and triggers an alarm if the intensity is reduced by 10% from the nominal of 15mW/cm2.
Describe the function(s) of the organisation and data justifying the need for the Initiative.
Assuming that the inverter is in the logic-1 state 50% of the time and in the logic-0 state 50% of the time, find the average power dissipation in a typical circuit. The power supply is 5 V.
In a particular logic-circuit technology, operating with a 3.3-V supply, the basic inverter draws (from the supply) a current of 60 μA in one state and 0 μA in the other. When the inverter is switched at the rate of 100 MHz, the average supply cu..
Using whatever numerical techniques appropriate determine a velocity versus time graph of his/her descent. Estimate the amount of free fall time that would be possible that would still allow full deployment of the parachute and a safe landing. Ign..
A 2 m x 2 m vertical plate is exposed on one side to saturated steam at atmospheric pressure and on the other side to cooling water that maintains a plate temperature of 50°C.
Strong cryptographic products are not allowed to export to certain countries in several counties, what are the pros and cons of the commercial use of strong cryptographic products?
A parachutist is in free fall at a rate of 180 ft/s when he opens his parachute at an altitude of 1900 ft. Following a rapid and constant deceleration, he then descends at a constant rate of 44 ft/s from 1800 ft to 100 ft, where he maneuvers the p..

For the logic circuit of Figure: write the logic expression for D in terms of A, B, and C directly from the logic diagram; construct the truth table and the Karnaugh map;
What are the benefits of digital manipulation (don't just think about photography)? What are the dangers of digital manipulation?
The L-beam illustrated in Figure is to carry, in addition to its own weight, a dead load g = 25 kN/m and a live load q = 100 kN/m over a simply-supported span of 8 m. Design and detail the tension reinforcement.
Consider the ripple counter of Figure. Suppose that the flip- flops have asynchronous clear inputs. Show how to add gates so that the count resets to zero immediately when the count reaches six. This results in a modulo-six counter.
