Step 1: Understanding processing contaminants.
- Nitrosamines are contaminants formed during food processing, especially in cured meats, due to reactions with nitrates at high temperatures.
Step 2: Explanation of incorrect options.
- Mycotoxins (A) and Aflatoxins (B) are naturally occurring toxins produced by fungi, not a result of food processing.
- Scombrotoxin (D): A toxin produced by bacterial spoilage of fish, not a processing contaminant.
Step 3: Selecting the correct option. Since Nitrosamines are produced during food processing, the correct answer is (C) Nitrosamines.
A closed-loop system has the characteristic equation given by: $ s^3 + k s^2 + (k+2) s + 3 = 0 $.
For the system to be stable, the value of $ k $ is:
A digital filter with impulse response $ h[n] = 2^n u[n] $ will have a transfer function with a region of convergence.
