| 11. | Digital filters rely less on analog circuitry, potentially allowing for a better signal-to-noise ratio.
|
| 12. | Similar effects can also be achieved with digital filter effects.
|
| 13. | There are two categories of digital filter : the recursive filter and the nonrecursive filter.
|
| 14. | Many digital filters are designed to give low-pass characteristics.
|
| 15. | There is an important difference between the design of 1-D and 2-D digital filter problems.
|
| 16. | Like his codes, Hamming's digital filters became indispensable parts of the digital engineer's tool kit.
|
| 17. | Analog signals can also be processed through digital filters by using Analog to Digital converters.
|
| 18. | This can be accomplished using reference lines, envelope methods, digital filters, fractals or other techniques.
|
| 19. | In addition to error correction, Hamming did pioneering work in digital filters while at Bell Labs.
|
| 20. | Signal communication USB, RS232 and digital filters implementation
