Transfer Function Analysis

DESIGN PHASE:       analysis
SUB ELEMENT NAME:   transfer function analysis
VARIABLE NAME:      [HEAX]
DATE:               REVISION LETTER:    REVISION DATE:   
APPLICABILITY:      regulator circuit

ACTIVITY:  Compute transfer functions (frequency plots) including
input impedance, output impedance, and audiosusceptibility.
Assumes use of Spice.

OUTPUT:  Calculations and plots to compare requirements and
measurements.

ALGORITHM:

[HEAX] =            engineer hours for transfer function analysis
0.0*[PARTS COUNT]+  set up time
0.0*                time per transfer function
[NX]                number of transfer functions
where
[NX] = [INPUT COUNT]+[OUTPUT COUNT]+[INPUT COUNT]*[OUTPUT COUNT]
