Design of low‐pass and band‐pass infinite impulse response maximally flat stable digital differentiators

IET Signal Processing, 2022
Maximally flat digital differentiators (MFDDs) are very attractive for differentiation of narrowband signals. The design of infinite impulse response (IIR) MFDDs, however, is very challenging due to the non‐convexity of the flatness constraints of the ...

A THz Spectrometer Using Band Pass Filters

Instruments, 2020
We describe a THz spectrometer operating between 1.2 and 10.5 THz, consisting of band pass filters made by metasurfaces. The source is made of a 10 W small black body. The detector is a high sensitivity room temperature pyroelectric sensor.
