6.

The power in the signal

*s*(*t*) = 8 cos (20 p - p/2) + 4 sin (15 p*t*) is7.

For the function

*f*(*t*) =*e**, the Laplace transform is*^{-at}8.

If

*f*(*t*) ↔ F(*j*ω),*f*(-*t*) ↔9.

**Assertion (A):** Transient analysis uses Laplace transformation.

**Reason (R):** Laplace transform method is suitable for solution of integro differential equations.

10.

The minor M

*of an*_{ij}*n*x*n*matrix is the determinant of (*n*- 1) x (*n*- 1) matrix formed by deleting the*i*th row and*j*the column of*n*x*n*matrix.Quick links
