Thanks to the new generation of digital receivers available at the IAR, developed by the CASPERcollaboration (Collaboration for Astronomy Signal Processing and Electronics Research), it is possibleto elaborate and implement new techniques for digital signal processing, increasing theobservational capabilities and flexibility of the radio telescopes of the IAR.The present work describes a proposal for the creation of a new high-bandwidth receiver,based on the ROACH (Reconfigurable Open Architecture Computing Hardware) board for thedetection and study of the radio transients known as Fast Radio Bursts (FRB). These areextremely rapid (∼1ms) flares that occur at cm-wavelengths of unknown origin. FRBs can beidentified because they shift in frequency due to the refractive effects of the interstellar medium.Here we describe the hardware that will be used, the software tool-flow already provided byCASPER, as well as the tools developed for the acquisition and processing of the signals.
