Which is a time varying response?
It is clear that the responses to both impulses are different: the dynamic behaviour has changed from the instant of the first impulse to the second. This is why the system is called time-varying. The impulse response of a time-varying system depends on the time at which the impulse has been applied.
Which is a time varying system?
A time-variant system is a system whose output response depends on moment of observation as well as moment of input signal application. In other words, a time delay or time advance of input not only shifts the output signal in time but also changes other parameters and behavior.
What is the meaning of time varying?
Time-varying volatility refers to the fluctuations in volatility over different time periods. Investors may choose to study or consider volatility of an underlying security during various time periods. For instance, the volatility of certain assets may be lower during the summer when traders are on vacation.

What makes a system time invariant?
A system is time-invariant if its output signal does not depend on the absolute time. In other words, if for some input signal x(t) the output signal is y1(t)=Tr{x(t)}, then a time-shift of the input signal creates a time-shift on the output signal, i.e. y2(t)=Tr{x(t−t0)}=y1(t−t0).
What is meaning of non volatile?
: not volatile: such as. a : not vaporizing readily a nonvolatile solvent. b of a computer memory : retaining data when power is shut off.
Is the output of a time variant system Tiv?
A time-variant system is a system that is not time invariant (TIV). Roughly speaking, its output characteristics depend explicitly upon time.
How is a time variant system solved mathematically?
Mathematically, there is a well defined dependence of the system over time and over the input parameters that change over time. In order to solve time-variant systems, the algebraic methods consider initial conditions of the system i.e. whether the system is zero-input or non-zero input system.
Can a system be considered to be time invariant?
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.
Is the linear-time variant system an impulse response?
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. Linear-time variant (LTV) systems are the ones whose parameters vary with time according to previously specified laws.
