SIGNALS & SYSTEMS

3. A signal satisfying the condition x(t) = x(t + T) or x(n) = x(n + N)
4. A system which satisfies superposition principles
6. A signal satisfying the condition x(t) = -x(-t)
8. A system which is memory-less
9. A system whose input appears at the output
10. Complex Fourier transform is also called as
11. Fourier transform pair of rectangular function
12. A signal satisfying the condition x(t) = x(-t)
14. Conditions necessary to satisfy to be able to represent a function in fourier transform

1. Series applicable only to periodic signals
2. a mathematical model to transform signals between time (or spatial) domain to frequency domain & vice versa
5. A system whose input and output characteristics vary with time
7. Signal expressed in mathematical form
8. A system whose output is bounded for bounded input is called
13. System where the output depends on past and current inputs but not future inputs
