Design a filter circuit to remove the noise signals while selectively amplifying the high-frequency signals by at least a factor of 100. The low-frequency noise signal has its peak energy in the vicinity of 20 Hz, and has fallen to less than 1 % of its maximum by 1 kHz. The engine failure signals begin in the vicinity of 25 kHz.

You are required to design an FIR digital filter for real-time extraction of a signal corrupted by noise. The signal information is in the 0 - 1500 Hz and 8000 -10000 Hz bands, while the noise has most of its energy in the 2000 Hz - 7000 Hz band. What kind of filter should you design for this application? A. Bandpass B. Lowpass C. Highpass D. Bandstop   For the same problem, what is the transition bandwidth parameter for designing a...

A common use of capacitors as a reactive component is in a low-pass or high-pass filter, both of which contain a resistor and a capacitor. A low-pass filter is one that passes through signals with frequencies lower than a particular cutoff frequency and causes attenuation in signals of higher frequency. A high-pass filter is one that passes through signals with frequencies higher than a certain cutoff and causes lower frequencies to attenuate, giving the two configurations their names. The cutoff...

Design an active-RC low pass second order Butterworth filter for a cutoff frequency of 1 kHz, and a pass band gain of 2 V/V. Use a 741 Op Amp. If using Table I, use a capacitor value of 0.1 μF for C and C1, otherwise you may use any capacitors available in the lab. If applicable, make an excel worksheet showing the calculations required for the above design.  Choose appropriate real resistor values for the designed circuit and simulate this circuit...
