The type-2 system has ________ at the origin.

The correct answer is: No net pole.

A type-2 system is a system that has a zero at the origin. A zero is a point where the system’s output is zero. In the case of a type-2 system, the zero is a simple zero, which means that it is a single point where the system’s output is zero. The system does not have a net pole, which means that the sum of the poles of the system is zero. A pole is a point where the system’s output is infinite. In the case of a type-2 system, there are no poles at the origin.

Here is a more detailed explanation of each option:

• Option A: No net pole. This is the correct answer. A type-2 system has a zero at the origin, but it does not have a net pole.
• Option B: Net pole. This is incorrect. A type-2 system does not have a net pole.
• Option C: Simple pole. This is incorrect. A type-2 system has a simple zero, not a simple pole.
• Option D: Two poles. This is incorrect. A type-2 system does not have two poles.
