Limit cycle oscillation due to Overflow | Digital signal processing | SNS Institutions

Limit cycle oscillation due to overflow is a phenomenon in digital filters where the output continues to oscillate even when the input signal is zero. It occurs because of arithmetic overflow in fixed-point DSP systems, causing errors in the feedback loop of recursive (IIR) filters. When the computed value exceeds the available register range, the result wraps around or saturates, introducing unwanted oscillations. #snsinstitutions #snsdesignthinkers #designthinking
