List of top Electronics Engineering Questions on Control Systems asked in CUET (PG)

If the number of zeros is less than the number of poles, i.e. \( Z<P \), then the value of the transfer function becomes zero for \( s \to \infty \). Hence, some zeros are located at infinity and the order of such zeros will be:
