T/F : FIR filters can be realized recursively and non recursively |
True |
|
|
T/F : IIR filters can be realized non-recursively. |
False. IIR filters can be realized only recursively |
|
|
For linear phase FIR filter, signal falling entirely in the passband will be reproduced with the delay equal to the _____ of the phase curve. |
signal falling entirely in the passband will be reproduced with the delay equal to the "Slope" of the phase curve. (In which phase?) |
|
|
Canonical form of representation |
if the order of difference equations is equal to the number of elements in the block diagram - CANONICAL FORM |
|
|
Non-Canonical structure |
If the number of block elements is not equal to the order of difference equations - NON CANONICAL FORM |
|
|
Advantages of block diagram representation of digital filter |
- 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 |
