A signal is made up of 3 sine waves of equal amplitude with frequencies F1 = 180 hz, F2 = 1200 Hz, and F3 = 2500 Hz. This signal is monitored using a DAQ and plotted on a FFT. The DAQ settings are Fsample = 4000 Hz, Nsample = 10,000. 1). Draw the resulting measured FFT below. 2). Draw the resulting measured FFT if the signal is passed through an analog Low Pass filter with a cutoff frequency of Fc = 400 Hz prior to measurement.

A 12-bit digital-to-analog converter has an output range of 0 to 10 V. Estimate the analog voltage output if the input is simple binary and has the decimal value of 45.
3. The results of a simple calibration of pressure transducer and its specification are shown in Figure 1 and Table 1. The sensitivity of the pressure sensor is 0.5 V/kPa (given by manufacturer) and the linear curve fit for the upscale calibration is given as y = 0.51x +0.02 . a) Calculate the hysteresis and linearity errors for this calibration. b) Please discuss either the pressure transducer can now be used for the actual measurement or not.

Problem 4-1: During a step function calibration, a first-order instrument is exposed to a step change of 100 units. If after 1.2 s the instrument indicates 80 units, estimate the instrument time constant. Estimate the error in the indicated value after 1.5 s. For this instrument, y (0) = 0 units; K = 1 unit/unit.

The output of a potentiometer is to be read by a recorder of 10,000 ohms input resistance. Nonlinearity must be held to 1 percent. A family of potentiometers having a thermal rating of 5 watts and resistances ranging from 100 to 10,000 ohms in 100- ohm steps is available. Choose from this family the potentiometer that has the greatest possible sensitivity and also meets the other requirements. What is this sensitivity if the potentiometers are single-turn (360°) units?
