A 5th Order Butterworth LPF having cutoff frequency 1 KHz. What is the approximate level of attenuation at 2 Khz frequency? 3 db 40 dB 30 dB 60 dB
Question
Solution 1
The level of attenuation for a 5th order Butterworth Low Pass Filter (LPF) can be calculated using the formula:
A = 20 * n * log10(f/fc)
where:
- A is the attenuation in dB,
- n is the order of the filter,
- f is the frequency for which we want to find the attenuation,
- fc is the cutoff frequency Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
