(a) A sensor has a transfer function of 0.5 mV/°C and an accuracy of ±2% If the temperature is known to be 80°C, what can be said with absolute certainty about the output voltage? (b) Suppose a reading of 60 mV results from the sensor of part (a). Find the temperature that could provide this reading.

In the operation of a half-wave rectifier with a capacitor-input filter, the ripple factor can be lowered by the value of the filter capacitor or + the load resistors.

Consider a 4-bit ADC and full scale voltage measurement range of (-37 to 37).The Resolution will be O 4.62 O 1.75 O 0.41 O 0.41 In CRO, if the electron beam emerging from the electron gun is left alone, it will strike the screen as straight line. Select one: OTrue O False

The sensitivity of a PMMC instrument is 10k /V. If this instrument is used in a rectifier type voltmeter with half wave rectification, the sensitivity will be:

Suppose we have a pressure sensor whose output is 0-10Vcorresponding to an input of 0-50 psi. We will use an 8-bit ADC withan input range of 0-10V to read the sensor. What is the finestresolution to which we can read the pressure?
