(a) A lirst order LPF (butterwarth) has a cul off frequency of $\mathrm{B} \mathrm{KI}-\mathrm{Iz}$ and unily gain al low frequency. Find the transfer function magnitude in dB at 14 KHz for the filler. 10
Explanation
The transfer function magnitude in dB is calculated using the formula 20log10(f/fc), where f is the frequency of interest and fc is the cut-off frequency. In this case, f = 14 KHz and fc = 1.1 KHz.
