The linear canonical transform (LCT) is a versatile integral transform that generalises classical transforms such as the Fourier, fractional Fourier, and Fresnel transforms. By utilising four ...

Chirp signals are fast, accurate, and provide information that may be more difficult to obtain in other ways, as Mark A Martin, Jayant Datta and Xinhui Zhou explain. Figure 1: The frequencies of the ...

Imec has come up with a novel digitally calibrated charge-pump (CP) phase-locked loop (PLL) that can generate high-quality frequency-modulated continuous-wave (FMCW) signals for mmWave radars at low ...
