Question
I. In the picture at the right, the input signal ( y = sin(4*n"t)) is fed into two filters (A) and (B). The input and the two outputs are labeled nput Output A Output B What is the frequency in Hz of the input signal? a. b. What is the magnitude of the input signal? Which filter (A) or (B) has the most attenuation of the input signal? c. Filter A is a first order Butterworth filter. The magnitude of the output signal after the filter is 1//2. What is the cutoff frequency of filter A? d. Filter B, is a 2nd order Butterworth filter. The magnitude of the output signal after the filter is 0.25. What is the cutoff frequency of filter B? e.Explanation / Answer
Answer
a) Frequency of Input signal is obtained by compairing it with standard Y= sin(wt).
hence w= 2pi and frequency 2
