Q. The process of converting an original cut-off frequency to new cut-off frequency is known as- Published on 23 Oct 15a. Frequency Deviation
b. Frequency Translation
c. Frequency Division
d. Frequency Scaling
ANSWER: Frequency Scaling
Frequency Scaling is a process of conversion of original cut-off frequency to a new cut-off frequency. Here, the frequency gets converted & not deviated or translated or divided before the conversion process. Frequency Scaling is most oftenly performed whenever there is a necessity to change the cut-off frequencies in filter designing process. Multiplication of either 'R' or 'C' by the ratio of original cut-off frequency to the new cut-off frequency gives a notion for changing the high cut-off frequency.
