What is the selectivity factor

Reference no: EM131021170

A low-pass filter is specified to have Amax = 2 dB and Amin = 12 dB. It is found that these specifications can be just met with a single-time-constant RC circuit having a time constant of 1 s and a dc transmission of unity. What must ωp and ωs of this filter be? What is the selectivity factor?
