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
A. -160dB/decade
B. -320dB/decade
C. -480dB/decade
D. -200dB/decade
Answer:A
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
A. -160dB/decade B. -320dB/decade C. -480dB/decade D. -200dB/decade
Explanation: For nth order filter the roll-off rate will be -n×20dB/decade.
