Abstract Equivalent‐time sampling can improve measurement or sensing systems because it enables a broader frequency band and higher delay resolution for periodic signals with lower rates than Nyquist receiver. Meanwhile, digital down‐conversion (DDC) technique be implemented using straightforward radio (RF) circuit. It avoids timing skew in‐phase/quadrature gain imbalance instead of requiring h...
