The first prototype of antialiasing filter for the CUORE experiment is a board that accommodates 12 independent channels. Each channel is an active six-pole Bessel–Thomson low-pass filter (LPF) with a roll-off of 120 dB/decade. In order to adapt the bandwidth to every detector, the filtering frequency can be selected independently for every channel by a remote control between four possible values (8, 12, 16 or 20 Hz). The board is equipped with an ARM microcontroller which communicates with the on-board peripherals via I2C synchronous serial bus and with the remote control via CAN-bus. Important features are the low-cost, the compact realization and the capability to perform diagnostic routine remotely

Abstract
The first prototype of antialiasing filter for the CUORE experiment is a board that accommodates 12 independent channels. Each channel is an active six-pole Bessel–Thomson low-pass filter (LPF) with a roll-off of 120 dB/decade. In order to adapt the bandwidth to every detector, the filtering frequency can be selected independently for every channel by a remote control between four possible values (8, 12, 16 or 20 Hz). The board is equipped with an ARM microcontroller which communicates with the on-board peripherals via I2C synchronous serial bus and with the remote control via CAN-bus. Important features are the low-cost, the compact realization and the capability to perform diagnostic routine remotely
