Solution:

What is a doublet function?

The output of an impulse function

The first derivative of an impulse function

Any continuous time impulse function has another name that is doublet function

A branch of an impulse function

Solution:

A system is said to be defined as non causal, when

the output at the present depends on the input at an earlier time

the output at the present does not depend on the factor of time at all

the output at the present depends on the input at the current time

the output at the present depends on the input at a time instant in the future

Solution:

For an N-point FFT algorithm with N=2^m, which one of the following statements is true?

It is not possible to construct a signal flow graph with both input and output in normal order.

The number of butterflies in the m-th stage is N/m.

In-place computation requires storage of only 2N node data.

Computation of a butterfly requires only one complex multiplication and two complex additions.
