In upcoming instrumentation, such as the SKA and SPOTLIGHT, realtime processing using high-performance computing accelerators such as GPU is planned. Such transient searches at lower radio frequencies are still more complex due to the more significant DM-related delays. This paper will review the transient detection techniques used for the Fast Radio Bursts in the existing Radio telescopes worldwide and describe a novel soft-realtime ( Analog and Digital ) approach for detecting transients being planned at Gauribidanur Observatory using a new infrastructure. An FRB out trigger station is already being planned in the same Gauribidanur observatory that operates in a higher frequency range between 400 to 800 MHz. We planned to establish a trigger functionality to enable low-frequency follow-up capabilities between the 150-350 MHz band. This paper will outline the details of the detection techniques in both analog and digital domains using the existing and upcoming infrastructure in Gauribidanur. |
