Given AB is parallel to DC Prove triangle ABE is congruent to triangle DCE

Mathematics
1 answer:
abruzzese [7]3 years ago
5 0
Answer: These two triangles can be proved similar by the AA Similarity Theorem. This states that you need angles in a pair of triangles to be congruent to prove they are similar.

In line 2, the angles are proved congruent because they are alternate interior angles.

In line 3, the angles are proved congruent because they are vertical angles. 

In line 4, you state the reason they are similar. (AA)

A minimum-phase continuous-time system has all its poles and zeros in the left-half s-plane. If a minimum-phase continuous-time
vlabodo [156]

Answer:

Yes, a minimum phase continuous time system is also minimum phase when converted into discrete time system using bilinear transformation.

Step-by-step explanation:

Bilinear Transform:

In digital signal processing, the bilinear transform is used to convert continuous time system into discrete time system representation.

Minimum-Phase:

We know that a system is considered to be minimum phase if the zeros are situated in the left half of the s-plane in continuous time system. In the same way, a system is minimum phase when its zeros are inside the unit circle of z-plane in discrete time system.

The bilinear transform is used to map the left half of the s-plane to the interior of the unit circle in the z-plane preserving the stability and minimum phase property of the system. Therefore, a minimum phase continuous time system is also minimum phase when converted into discrete time system using bilinear transformation.
