The option that is not a deterministic signal is this: c. Noise
What is not a deterministic signal?
A deterministic signal is one whose future values can be perfectly predicted based on its past and present values. Noise is non-deterministic because it is unpredictable and random. Its future values cannot be precisely predicted based on its past or present values.
This inherent randomness is what differentiates noise from other signals in the options so it is not a deterministic signal. Sine and Cosine waves are periodic signals with well-defined mathematical formulas.
