Design a band-stop filter to eliminate a 50 Hz interference in an audio system. You want the depth of the notch to be at least 20 dB. What values of R and C would you choose assuming a Twin-T filter?
💡 Hint: Use the relationship of R and C to determine the fnotch as specified.
In a specific circuit, the bandwidth of a band-stop filter is measured at 10 Hz with a notch frequency of 500 Hz. What would the filter’s performance look like with respect to frequencies close to 500 Hz?
💡 Hint: Consider how deep the notch affects frequencies at both the edges of the BW.
