Nov 19^th, 2008, 9:23pm Hi Guys, How do I get the frequency where the maximum magnitude is for a bandpass filter? The design environment is ADE+wavescan in Cadence ICFB 5.10.41. I want to calculate/measure it automatically. Thanks Yawei

ocnHelp 'xmax

PROTOTYPE xmax( o_waveform x_numberOfPeaks ) =>
o_waveform/g_value/l_value/nil

DESCRIPTION Computes the value of the independent variable
(X) at which the Y value attains its maximum value.

EXAMPLE(S)
xmax( v( "/net9" ) 1 )

Gets the time value (X-axis value) at which the voltage of
"/net9" attains its first peak value.

xmax( v( "/net9" ) 0 )

Gets the list of time values (X-axis values) at which the
voltage of "/net9" attains each of its peak values.
