- Calculate transmittancearrow_forwardAn absorption measurement with a 1 cm path length yields a reading of 0.004 absorbance units with a noise of 0.001 absorbance units and a mean noise reading of 0 for 10 scans averaged together. Assuming the noise for a single scan does not change if the path length is increased to 6 cm and the number of scans is increase to 100, what is the signal to noise of the new measurement.arrow_forwardPlease with brief explanation. a. Does changing the ramp generator will change the amplitude of a free-running triangle wave generator? b. Does changing the time constant of the Schmitt Trigger will change the frequency in a free-running triangular wave generator? c.
