The first two systems are non-causal because of the inputs like -Pi and and -1 which are plugged into the first two systems respectively ; leading to future values of the input whereas the last system is causal because the output depends on the past value of the input.
Trigonometric-Functions repeat themselves always between -1 and +1. So the value of the Output of the first one Y(t) = X(sin "t") is always more than the value in parentheses of X. That means it is Causal, because the Output depends on a value smaller than itself which means again "past"!

Homework question solutions: All are casual 1.if we put t=π(3.14 approx) y(3.14)=x(sin π) ,we know that sinπ=0 y(3.14)=x(0) which means past input .so it is casual system. 2. If we put t=4 y(4)=x(4÷4) y(4)=x(1) , which means past input ,so it is a casual system 3. exponential is coffecient if you put t=1 y(1)=e^2*1 x(1-0) y(1)=e^2*1 x(0) which means past input it is a casual system.

sir in the 3 question that u solved for t= 1, here at t=1 sin(2)....this 2>1...it is depending on future value also it should be non causal but u said it causal ..plz explain it.
put t=-pi/2 i.e, -3.14/2=-1.57 u will get y(-1.57)=x(-1). so, present value is depending on future value as -1 is greater than -1.57. So, Non causal system.

Can anyone explain y(t) =x(e^t) .
Apart from t=0, output depends on e .
It will only depend on output.
So it should be ante causal system.
All anti-causal systems are non-causal systems (not vice versa). We are only checking for causal and non-causal systems. And at t

t>=sin(t ) so for any value of function x(sin(t)) system is causal system.
check for -pi/2
for t=pi/2,
y(1.5)=x(1) for output is always depending on past values.
So causal.

Sir why u have not mentioned anti causal? Y(t) =x(e^t) will be anti causal.. because it is dependent only on future value.. am i right? Please reply
Same doubt bro
Yes
because y(0) = x(e^0) => y(0) = x(1); x is a future input and e^0 equals 1 you can try it on your calculator
It is both anticausal and non causal

4th should be anti causal. For each output it depends only on future input
Anti causal systems dont exist only causal and non-causal systems are available
sir in 4th example o/p value depends only on future value of input the it should be anti causal not non - causal.
Every anti-causal sys is non causal and the opposite is wrong

we cant differ bw causal and dynamic system because time scaling is involed in both system and that makes me dizzy
Why do you only test for t = 0 / t=1 as for when t=4 tested on system x(t-1) , = x(3) hence it is reliant on future input?
With respect to t=4 i.e. Y(5)...x(3)is past input

1st how come non-causal..sir pls explain..
see manisha !! if u get even a single future value, then the system is termed as non-causal (bcz causal system does not contain any future value)
put t=-pi/2 i.e, -3.14/2=-1.57 u will get y(-1.57)=x(-1). so, present value is depending on future value as -1 is greater than -1.57. So, Non causal system.
the last 4 solved problem,it depends only on the future,so it should be anti causal and not non causal, #nesoacademy
