### Find what is its cut-off frequency of a low pass filter

Assignment Help Electrical Engineering
##### Reference no: EM13256553

1. For a first order low pass filter, with a cut-off of 2 kHz, how many decades and octaves would the frequency be if the attenuation was -58 dB? What would the frequency be at that attenuation?

2. If the filter in the first problem was a first order high pass filter, with the same cut-off frequency, what would the two answers be?

3. If you had a second order low pass filter, and at 100 kHz the attenuation was -64 dB, what is its cut-off frequency?
