Explanation: A narrow band-reject filter is also called as notch filter because of its higher quality factor, Q (>10). 4. Find the expression for notch-out frequency?
A. fN = 2πRC
B. fN = 2π/RC
C. fN = 1/2π×√(R/C)
D. fN = 1/2πRC
Answer:A
Explanation: A narrow band-reject filter is also called as notch filter because of its higher quality factor, Q (>10). 4. Find the expression for notch-out frequency?
A. fN = 2πRC B. fN = 2π/RC C. fN = 1/2π×√(R/C) D. fN = 1/2πRC
Explanation: The notch-out frequency is the frequency at which maximum attenuation occurs: it is given by fN =1/2πRC. 5. The quality factor of passive twin T-network is increased by using
