Dear Members,

Could someone please help me with the interpretation of "72 descending 3
dB/oct above 0.03 MHz" for the frequency range of 0.009<=f<0.090 MHz?

Does it mean:
for the frequency range of 0.009 to 0.030 MHz, the limit is 72,
for the frequency rage of 0.030 to 0.090 MHz, the limit is "72 descending 3
dB/oct"?

Thank you very much for your time and I look forward to hearing from you.

Best regards,
Grace Lin
