Step 1: Understanding Biopolymers
Biopolymers are naturally occurring polymers produced by living organisms, including polysaccharides, proteins, and nucleic acids.
Step 2: Evaluating the Options
- Scleroglucan: A polysaccharide biopolymer produced by fungi.
- Aconitase: An enzyme, not a biopolymer.
- Lyase: An enzyme, not a biopolymer.
- Phenyl acetic acid: A small organic compound, not a biopolymer.
Step 3: Conclusion
Scleroglucan is the correct example of a biopolymer.
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.
