Component values will change over the years but the only problem which most people will worry about is tolerence in component values when the device is first made, component values will follow a Gaussian distribution so your design has to be able to work with that tollerance in component values, they way you do that with things like amplifiers and filters is to perform whats called a sensitivity analysis which shows how the overall transfer function of a system varies with changes in component values.Some types of filters are wildly sensitive to component changes and some are not.There are analytical methods for doing sensitivity analysis but most simulators just use Monte carlo methods. |
