If δPis the forbidden magnitude value in the pass band and δS is the forbidden magnitude value in th stop band, then which of the following is true in the stop band region?
A. 1- δP≤|H(jΩ)|≤1
B. δP≤|H(jΩ)|≤1

D. 1- δP≤|H(jΩ)|≤1
Answer:A
If δPis the forbidden magnitude value in the pass band and δS is the forbidden magnitude value in th stop band, then which of the following is true in the stop band region?
A. 1- δP≤|H(jΩ)|≤1 B. δP≤|H(jΩ)|≤1 C. 0≤|H(jΩ)|≤ δS D. 1- δP≤|H(jΩ)|≤1
Explanation: From the magnitude frequency response of the low pass filter, the hatched region in the stop band indicate forbidden magnitude value whose value is given as
