Abstract: This letter examines truncation errors in hierarchical beamforming networks (BFNs) using layered time delay units (TDUs). While quantization errors are assumed to be bounded by half the ...

Problem 1: Approximate (sin(x)) using a truncated Taylor series expansion. The function takes inputs (x) and truncation order (N), returning the series approximation. Truncation errors are analyzed by ...

Abstract: The existing frequency-limited interval-based model reduction techniques can generate unstable models for a stable continuous-time linear system. Further ...
