Unreferenced date September 2007 A time variant system is a system that is not time invariant systemtime invariant TIV . Roughly speaking, characteristics of its output depend explicitly upon time. Overview There are many well developed LTI system theory techniques for dealing with the response of linear time invariant systems, such as Laplace Transform Laplace and Fourier Transform Fourier transforms. However, these techniques are not strictly valid for time varying systems. A system undergoing slow time variation in comparison to its time constants can usually be considered to be time invariant they are close to time invariant on a small scale. An example of this is the aging and wear of electronic ... different from that observed in a time invariant system day to day, they are effectively time invariant, though year to year, the parameters may change. Other linear time variant systems may behave more like nonlinear systems, if the system changes quickly significantly differently between measurements. The following things can be said about a time variant system It has explicit dependence on time. It does not have an impulse response in the normal sense. The system can be characterized by an impulse response except the impulse response must be known at each and every time instant. It is not stationary Examples of time variant systems The following time varying systems cannot be modelled by assuming that they are time invariant Aircraft Time variant characteristics are caused ... solar radiation varies with time due to changes in the Earth s albedo and the presence of greenhouse gasses in the atmosphere.

A time invariant TIV system is one whose output does not depend explicitly on time. If the input signal math x t math produces an output math y t math then any time shifted input, math x t delta math , results in a time shifted output math y t delta math This property can be satisfied if the transfer function of the system is not a function of time except expressed by the input and output.

unreferenced date July 2008 Time Sharing Operating System , or TSOS , was an operating system for Radio Corporation of America RCA mainframe computer s of the RCA Spectra 70 Spectra 70 series. RCA was in the computer business until 1971. Then it sold its computer business to Sperry Corporation Sperry offered TSOS renaming it to VS 9 . In the mid seventies, an enhanced version of TSOS called BS2000 was offered by the German company Siemens . While Sperry Unisys after the company was renamed discontinued VS 9 in the early 80 s, BS2000 , now called BS2000 OSD is still offered by Fujitsu Siemens Computers and used on their mainframe customers primarily in Europe. TSOS was the first operating system that supported virtual addressing of the main storage. As the name suggests, it provided time sharing features. Beyond that it provided a unique user interface for both time sharing and batch which was a big advantage over IBM s OS 360 or their successors MVS , OS 390 and z OS .
