Claims
- 1. A method of forming an adapter for utilizing a PCMCIA card having PCMCIA bus architecture thereon, in a desktop computer which has at least one logic card slot and one bay and which bus architecture is different from the PCMCIA bus architecture, comprising the steps of:
- a. providing logic circuitry for converting a PCMCIA bus to the bus architecture of a desktop computer;
- b. providing an outrigger card having at least one PCMCIA card adapter thereon;
- c. connecting said outrigger card to said logic circuitry by a flexible cable having a plurality of wires for bidirectional conveying of signals by said wires;
- d. providing a plurality of conductors on said outrigger card connecting the wires of said cable to said PCMCIA card slot;
- e. inserting a PCMCIA card in said PCMCIA slot;
- f. generating signals between said logic circuitry and said PCMCIA card slot over said cable and said conductors;
- g. determining which signals have a noise component greater than a predetermined minimum;
- h. calculating the value of noise component of each signal having a value greater than the predetermined minimum,
- i. calculating the value of a capacitor which would theoretically eliminate the value of each of said signal noise components;
- j. providing a capacitance equal to the calculated value across each of the conductors for which the value was calculated and a plane on a predetermined voltage;
- k. redetermining which of said signals on the conductor having a capacitor across the conductors have a noise value above said preselected level;
- l. increasing the capacitance on each conductor when said redetermined value of step k is greater than said predetermined value; and
- m. repeating steps k and l until the noise level is below said preselected level for all conductors.

- V=(1/C).times..intg. of i by dt
- where C=Capacitance
- i=Current
- t=Time.
- 4. The method as defined in claim 1 wherein the noise component value calculation in step h is calculated using the equation:
- V=L(di/dt)
- Where: V=Volts
- L=Inductance
- i=Current, and
- t=Time
- and the calculation of the value of the capacitor in step i is calculated using the equation
- V=(1/C).times..intg. of i by dt
- where C=Capacitance
- i=Current
- t=Time.
