False
True
Time scaling is an operation performed by
Dependent variable
Independent variable
Both dependent and independent variable
None of the above
Y(t)=x(t/5) is
Compressed signal
Expanded signal
Time shifted signal
Amplitude scaled factor by 1/5
Fundamental period of 3cos4t+2sin (2pi)t
2/5 sec
It is a periodic signal
0.2 sec
It is not a rational number
Invertibility of the system y(t)=x^2(t) is
2x^-1(t)
X^2(t)/2
Doesn't exist
Some rational number
Y(t)=x^2(t) is
Linear
Non linear
Cannot be defined
If there is a one to one mapping between input and output,then the system is said to be
Stable
Invertible
Both stable and invertible
Time variant
A memory less system is causal, but a causal system cannot be memory loss
True
False
Is the signal x(t)=exp(-t)sin(t) periodic in nature?
Yes
No
Random signals are
Power signals
Energy signal
Periodic
Both periodic and energy
A system with memory which anticipates future values of input is called
Causal system
Non causal system
Stable system
Non anticipative system
A signal is non causal if
X(t)=0 for t=0
X(t)=1 for t<0
X(t)= 1 fort>0
X(t)=0 for t>0
In the equation x(t)=be^at if a<0 then it is called
