You have been hired to develop two software packages for the analysis of 10-channel EEG signals for the following purposes:

(a) Detection of the presence of the alpha rhythm: (i) in any one single channel and (ii) jointly in a pair of left-right channels.

(b) Detection of spike-and-wave complexes of a prespecified shape in any channel.

Design two signal processing packages to address the two problems mentioned above. For each package, provide the following details:

(i) A schematic block diagram representing the various algorithms or signal processing steps that you recommend. Include at least three distinct and nontrivial procedures in your design.

(ii) Explain each block or part of your package.
