Concept explainers

Filter

A filter is a device or process which removes some of the unwanted features or components like frequencies from a signal in signal processing. The feature of filters is the complete or partial suppression of some part of the signal, and filtering is a class of signal processing. This most often means removing some frequency bands or some frequencies. In the frequency domain, the filters do not exclusively act, especially in the image processing field many other targets for filtering exist. Without having to act in the frequency domain, the correlations can be removed for certain frequency components and not for others. The filters are widely used in electronics and telecommunication, in television, radio, radar, audio recording, music synthesis, control systems, computer graphics, and image processing.

Electrical Engineering hi expert , how to do this question? A signal transmission line will be used to carry measurement data as a frequency (a) modulated signal from 8 kHz to 10 kHz. The line is shared with voice data below 600 Hz, and switching noise occurs above 150 kHz. A band-pass RC filter is used to reduce the voice by 80 % and the switching noise by 90 %. Use resistance ratio of r= 0.01. Design a band pass RC filter by using the available electronic components which are two capacitors (4.7 pF and 2.46 nF) and two resistors (2.2 MSN and 22 kN). With the filter design, determine the low band frequency (fi) and the high band frequency (fr). Draw the band pass RC filter with proper labeling. (i) Based on the band pass RC filter design in Q4 (a)(i), evaluate the attenuation of the measurement data if the frequency modulated signal is operated at 9 kHz.
