The D/A converter in a CD player must convert 16-bit binary numbers to analog voltage values. If you were to extend your binary-weighted DAC design to 16 bits with the output voltage level between 0 V and -5V, which resistor values would be needed in your circuit?

2, 2.3, 2 1. Design 3 bit Analog to digital converter. 2. Consider a platinum resistance temperature sensor, which has a resistance at 0°C of 100 ohms and forms one arm of a Wheatstone bridge. The bridge is balanced, at this temperature, with each of the other arms also being 100 ohms. If the temperature coefficient of resistance of platinum is 0.0039/K, what will be the output voltage from the bridge per degree change in temperature if the load across the output can be assumed infinite? The supply voltage, with negligible internal resistance, is 6.0v. The variation of the resistance of the platinum with temperature can be represented by Rt = R0(1+ at) Where Rt is the resistance at t (°C), R0 the resistance at 0°C and a the Temperature coefficient of resistance. 3. Simplify the Boolean function below and draw the Combinatorial logic of Simplified Function. (a + b)(a + b') 4. Implement a logic function and circuit diagram of truth table below. ABC F A 5.

1. For the pointer position in the diagram, what is the input signal if the range is set at 0.3 V? A. For the pointer position in the diagram, what is the input signal if the range is set at 1 V? B. For the pointer position in the diagram, what is the input signal if the range is set at 30 V? C. Let’s say you know that the input signal will be about -0.25 V. What range should you select to give maximum deflection without going off scale? Draw a line, with a straight-edge, on the picture above, showing how the pointer would point.
