Meaning of 3 dB cutoff frequency
Illustrate the meaning of 3 dB cutoff frequency? Explain why it is3 dB, not 1 dB?
Expert
3db entails 70 % (o.7o7) of the power, that is, interested to consider the bandwidth range from peak to 70% because up to70% it’s reliable. Therefore 3db is termed as half power frequency. 3db value is the mean square value that is 70% of the maximum value.
