EML 3523C Experimental Methods Summer 2021 Final Exam: 8:30-10:30 AM Monday, Aug. 02, 2021 Online Open Textbook only Student Name: fade KCheces Mere Problem No. 1(25 Points) Problem No. 2(25 Points) Problem No. 3(20 Points) Problem No. 4(30 Points) Total: Problem 1 (25 Pts) Design a low pass multistage Butterworth filter that simultaneously meets the following design requirements: 1. Minimum attenuation of 24 dB at 1000 Hz and 2. Minimum attenuation of 48 dB at frequency of 2000 Hz or higher. Consider equal source and load impedances at 50 Q. Part a) 15 pts Solve for both the order of the Butterworth filter and the cut-off frequency required to meet the above design criteria. Part b) 10 pts Find the values of the capacitors and inductors required to construct the filter and draw the circuit diagram of the filter with all the required components. , [2 800)244 a) 345104, > j LUG) 3 bala 7 eee = Ke init - : v + Gc Q Mert tT) - dalle -1 {ht Lace ) A> hst- UnGaad BATE Lal Mees is MTS SiG Problem 3 (20 points) A stain gauge differential pressure transducer with a range of 0 to 100 psi is to measure a pressure difference of 50 psi, with the following specifications: Output range: 0 to 10 Volts Linearity Error: +/- 0.1% of reading Hysteresis Error: +/- 0.05% of reading Sensitivity Error: +/- 0.01% of reading When transducer is installed for its intended use, installation effects are estimated to affect its reading by 0.1 psi. The output is measured using a 12 bit A/D converter with input range of 0 to 10 volts. The analog voltages recorded by the A/D converter are accurate to within +/- 0.1% of the readings. Estimate the uncertainty associated with the differential pressure measurement using the installed pressure twansducer-A/D converter system. Egsa Q- r oe lo uz \ (0.1) 4 Goo5¥' (01) Gaon .
