October 2024 Monthly Summary: Delivered multi-input arithmetic blocks for signal processing in fair-acc/gnuradio4, enabling variable-port operations for add, subtract, multiply, and divide. The blocks support a dynamic number of inputs, improving flexibility for complex signal chains and reusability across projects. Implemented refactor to accommodate variable inputs and introduced comprehensive unit tests to verify correctness across multiple arithmetic types. The changes reduce integration effort for users building custom signal-processing pipelines and lay groundwork for scalable arithmetic blocks in GNURadio workflows.
