Question

Why is the computer necessary in Fourier Transform Spectrometer?

(a) To display the detector output

(b) To process the detector output

(c) To determine the amplitude

(d) To determine the frequency

I got this question during a job interview.

My question comes from Fourier Transform Infra-red Spectrometers topic in chapter Colorimetry and Spectrometry of Analytical Instrumentation

Answer 1

Correct answer is (b) To process the detector output

For explanation: The computer is necessary to process the output of the detector. The Fourier Transform of output is determined using software using computers.
