hello guys,
Plz show me theoritically how this system: y(t) = x(2t) is linear(i.e it has the properties of scaling and superposition) and also how it is non casual.
Thanks

If you can understand the explanation, you can do the tests yourself. Plug it into the expression for superposition and see if it's true (note: if superposition holds, so does scaling). Then see if the system shows an output before it gets an input to show it's non causal.
