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
A. Inverting amplifier
B. Non-inverting amplifier
C. Voltage follower
D. Differential amplifier
Answer:A
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
A. Inverting amplifier B. Non-inverting amplifier C. Voltage follower D. Differential amplifier
Explanation: The passive twin T-network has a selectively low figure of merit. The Q of the network can be increased significantly, if it is used with the voltage follower. 6. Find out the application in which narrow band-reject filter can be used?
