Front 3

Transfer function of IIR systems

Back 3

Hint 3

Summation k=0 to M (Bk z^(-k)) / 1 + summation k=1 to N (Ak z^(-k))

Front 4

Transfer function of FIR system

Back 4

Hint 4

Summation k=0 to M-1 (Bk z^(-k))

Front 5

T/F : FIR filters can be realized recursively and non recursively

Back 5

True

Front 6

T/F : IIR filters can be realized non-recursively.

Back 6

False. IIR filters can be realized only recursively

Front 7

For linear phase FIR filter, signal falling entirely in the passband will be reproduced with the delay equal to the _____ of the phase curve.

Back 7

signal falling entirely in the passband will be reproduced with the delay equal to the "Slope" of the phase curve. (In which phase?)

Front 8

Canonical form of representation

Back 8

if the order of difference equations is equal to the number of elements in the block diagram - CANONICAL FORM

Front 9

Non-Canonical structure

Back 9

If the number of block elements is not equal to the order of difference equations - NON CANONICAL FORM

Front 10

Advantages of block diagram representation of digital filter

Back 10

- Computational algorithm can be easily written.

- memory requirement can be determined easily

- block diagram can be determined by a transfer function

- relationship between input and output can be determined easily
