LF: Playing with Pspice

["Alberto di Bene" <dibene@usa.net>]

Hi all,
  today I fired up Pspice, just to see if I remembered how to use
it, and somehow came up with a lowpass circuit for 137 Khz, which
uses standard value components, and has 50 ohm input and output
impedance. It is flat from 0 to 138 kHz, and exhibits about 60 dB
of attenuation at 300 kHz.

In case someone is interested, here is the schematic and the 
Bode plot, also with a couple of cursors to measure the 
attenuation values.
