Question

Which of the following techniques are not included in the transformation domain category?

(a) Wavelet transform

(b) Discrete cosine transform

(c) Fourier descriptors

(d) Combine discrete cosine and Fourier transform

This question was posed to me during an internship interview.

This is a very interesting question from Central Monitors in section Patient Monitoring System of Biomedical Instrumentation

Answer 1

The correct answer is (d) Combine discrete cosine and Fourier transform

The explanation: In the transformation domain category, ECG samples are transformed to another domain. Examples include Fourier descriptors, discrete cosine transform, wavelet transform and combine discrete cosine and wavelet transform.
