Explanation: The frequency, f=fH is called cut-off frequency, because the gain of the filter at this frequency is down by 3dB from 0Hz. Cut-off frequency is also called as break frequency, corner frequency or 3dB frequency. 7. Find the High cut-off frequency if the pass band gain of a filter is 10.
A. 70.7Hz
B. 7.07kHz
C. 7.07Hz
D. 707Hz
Answer:A
Explanation: The frequency, f=fH is called cut-off frequency, because the gain of the filter at this frequency is down by 3dB from 0Hz. Cut-off frequency is also called as break frequency, corner frequency or 3dB frequency. 7. Find the High cut-off frequency if the pass band gain of a filter is 10.
A. 70.7Hz B. 7.07kHz C. 7.07Hz D. 707Hz
Explanation: High cut-off frequency of a filter, fH=0.707×AF =0.707×10
