Focus on Op-amp U2 (*Both op-amps have to be completely connected as shown in Figure A) Use myDAQ’s oscilloscope to capture the intermediate output waveform Vout1 (on Channel 0) and the final output waveform Vout2 (on Channel 1) superimposed. Set the amplitude scale of the oscilloscope for Channel 0 to 500 mV/Div, and for Channel 1 to 2 V/Div. Set the time scale of the oscilloscope to 500 us/Div   Take a screenshot of the oscilloscope (both waveform in the same picture) and embed the screenshot as the answer for this question. Report the value of Vout1(p-p) and Vout2(p-p) observed from the oscilloscope. Calculate the experimemtal Gain2=?

Compare your experimental results to the previously-computed theoretical values. Explain your observation from the oscilloscope output waveform.

Op-amp U1 & U2 Use myDAQ’s oscilloscope to capture the input waveform Vin (on Channel 0) and the final output waveform Vout2 (on Channel 1) superimposed. Set the amplitude scale of the oscilloscope for Channel 0 to 500 mV/Div, and for Channel 1 to 2 V/Div. Set the time scale of the oscilloscope to 500 us/Div   Take a screenshot of the oscilloscope (both waveform in the same picture) and embed the screenshot as the answer for this question. Report the value of Vin(p-p) and Vout2(p-p) observed from the oscilloscope. Calculate the experimemtal Gaintotal=?

Calculate the amount of unconjugated bilirubin in the patient with the following laboratory test results: (I.17) Total serum bilirubin = 20 μmol/L Conjugated bilirubin = 10 μmol/L ALP    mildly elevated AST    markedly elevated ALT    moderately elevatged ALB    decreased γ-Globulin    increased  

A 21 year old man with nausea, vomiting and jaundice has the following laboratory findings:   Total serum bilirubin               8.5 mg/dl (0 – 0.1 mg/dl) Conjugated serum bilirubin      6.1 mg/dl (0 – 0.5 mg/dl) Urine urobilinogen                  increased Fecal urobilinogen                  decreased Urine bilirubin                        positive (negative) AST                                      300 U/L (0 – 50 U/L) ALP                                      900 U/L (0 – 150 U/L)   These results can best be explained as representing:  (I.14)

Amino acids are broken down by the liver into ammonia and:  (G.4)

In the Jaffe reaction, a red-orange chromogen is formed when picrate (picric acid) reacts with:  (G.9)

IgA (an antibody found in secretions) (D.24)

IgG (main serum antibody) (D.24)

What is a function of serum proteins? (D.9)
