The spectra provided by the FFT subsystem are correlated to provide the cross power spectrum by the Multiply and Accumulate Subsystem. This is the crucial subsystem responsible for the realisation of a 30-by-30 array. Inputs from all the 30 stations of G.M.R.T. are fed into this array to compute the cross power spectra arising from the 465 pairs for each spectral component and polarisation.
The MAC subsystem comprises of the following :
1.MAC Card
2.MAC Control Card
3.MAC Backpanel
4.MAC Power Supply
5.MAC Clock Supply
6.MAC Testing Procedures
7.MAC Packaging
