← Logic & PuzzlesIf a signal-processing engineer applies singular value decomposition (SVD) to a matrix representing an audio signal, which consequence follows regarding noise reduction?
A)Noise is amplified uniformly.
B)Dynamic range remains unaffected.
C)Noise is suppressed selectively.✓
D)Latency increases exponentially.
💡 Explanation
SVD decomposes the matrix into singular values representing signal strength; smaller singular values, often associated with noise, can be zeroed or reduced. Therefore, noise is suppressed selectively rather than amplified, because SVD allows targeted filtering.
