Question: A student designed a low-pass filter with a required cutoff frequency of 1000 Hz using the circuit of Figure 124. When he measured the output

A student designed a low-pass filter with a required cutoff frequency of 1000 Hz using the circuit of Figure 12–4. When he measured the output at the −3 dB frequency, he was surprised that the output had decreased by 16:1 dB. He checked his values of R and L and their ratio R=L = 1000, just as he designed it. What did he do wrong?
