Explanation: Although higher order filter than necessary gives a better stop band response, the higher order type is more complex, occupies more space and is more expensive. 11. The overall gain of higher order filter is
A. Varying
B. Fixed
C. Random
D. None of the mentioned
Answer:A
Explanation: Although higher order filter than necessary gives a better stop band response, the higher order type is more complex, occupies more space and is more expensive. 11. The overall gain of higher order filter is
A. Varying B. Fixed C. Random D. None of the mentioned
Explanation: The overall gain of higher order filter is fixed because all the frequency determining resistor and capacitors are equal. 12. Find the roll-off rate for 8th order filter
