Which of the following filters cannot be designed using impulse invariance method?

The impulse invariance method and mapping of derivatives are inappropriate to use in the designing of high pass and band pass filters due to aliasing problem.

A

True

B

False

By impulse invariance method, the IIR filter will have a unit sample response h(n) that is the sampled version of the analog filter.

A

True

B

False

The zero positions obtained from matched z-transform and impulse invariance method are not same.

A

True

False

We can employ the analog frequency transformation followed by conversion of the result into the digital domain by use of impulse invariance and mapping the derivatives.

A

True

B

False

Instead of glass filters, why gelatin filters could not be used for a long period while both are Absorption filters?

A

Gelatin tends to evaporate and hence they deteriorate

B

Gelatin is affected by humidity in the environment

C

They deteriorate due to absorption of heat leading to changes in gelatin

D

Gelation is affected by temperature in the environment
