SUMMARY

The discussion clarifies the functionality of the MATLAB command filter(chan, data), emphasizing its distinction from convolution. Users are encouraged to compare the outputs of the conv and filter commands using known sequences to observe the differences in vector lengths and outputs. This hands-on approach reveals that filter operates differently than conv, providing insights into its application in signal processing.

PREREQUISITES
  • Understanding of MATLAB programming environment
  • Familiarity with signal processing concepts
  • Knowledge of convolution and filtering techniques
  • Ability to manipulate vectors in MATLAB
NEXT STEPS
  • Explore MATLAB's conv function in detail
  • Investigate the mathematical principles behind digital filtering
  • Learn about the filter command's parameters and options
  • Study practical applications of filtering in signal processing
USEFUL FOR

Signal processing engineers, MATLAB users, and anyone interested in understanding the differences between filtering and convolution in digital signal processing.

can anyone tell me please what does filter(chan,data) really works ie is it conv or what as i need inverse that operation in the reciever,
its urgent please

Take a two sequences that you know what the convolution of the two will be. Then, under two separate variables find the vectors produced by the 'conv' command and then the 'filter' command. Compare the lengths of the vector outputs, then the output by graphing or manually comparing. The operation of 'filter' should become fairly obvious.
