The digital backend is the section of the G.M.R.T. which deals with the digital conversion, manipulation and storage of the analog signals comming from the baseband system. The signal from the antenna after going through the baseband system is analog in form. This signal needs to be converted into digital form , so that it could easily be worked upon using digital signal processing. The signal after being converted into digital form is processed through FX Correlator to generate cross amplitude and phase information among the 30 antennas to synthesise the Stokes Prarameters. The output from the correlator ( FFT subsystem ) are given in parallel to the Array Combiner for generating the Incoherent Array ( IA ) and Phased Array ( PA ) outputs for pulsar observations.
