SECTION 6 DIGITAL FILTERS
The key difference between analog and digital filters is that instead of calculating resistor capacitor and inductor values for an analog filter coefficient values are calculated for a digital filter So for the digital filter numbers replace the physical resistor and capacitor components of the analog filter |

CHAPTER 8 ANALOG FILTERS
ANALOG FILTERS INTRODUCTION 8 1 CHAPTER 8: ANALOG FILTERS SECTION 8 1: INTRODUCTION Filters are networks that process signals in a frequency-dependent manner The basic concept of a filter can be explained by examining the frequency dependent nature of the impedance of capacitors and inductors |

INTRODUCTION TO DIGITAL FILTERS
Analog and digital filters In signal processing the function of a filteris to remove unwanted parts of the signal such as random noise or to extract useful parts of the signal such as the components lying within a certain frequency range The following block diagram illustrates the basic idea |
Should a digital filter be used?
Lastly, the analog filter The digital filter overshoots about both are bad, no points are awarded. In spite of this beating, there are should, or must, be used. This is not filter (i.e., what goes in and what analog circuits have over digital speed : digital is slow; analog is fast.
What are analog and digital filters in signal processing?
Analog and digital filters In signal processing, the function of a filteris to remove unwanted parts of the signal, such as random noise, or to extract useful parts of the signal, such as the components lying within a certain frequency range. The following block diagram illustrates the basic idea.
How do I Choose an analog filter?
This analog filter can be chosen using a design from TI (Figure 3). This circuit is a Sallen-Key design with a Butterworth-type response. This design allows one to easily choose the resistor and capacitor values to achieve the desired cutoff frequency at 5 kHz.
How does a digitalfilter work?
A digitalfilter uses a digital processor to perform numerical calculations on sampled values of the signal. The processor may be a general-purpose computer such as a PC, or a specialised DSP (Digital Signal Processor) chip. The analog input signal must first be sampled and digitised using an ADC (analog to digital converter).
