Photon Frequency Mode Matching using Acousto-Optic Frequency Beam Splitters [PDF]
, 2005 It is a difficult engineering task to create distinct solid state single photon sources which nonetheless emit photons at the same frequency. It is also hard to create entangled photon pairs from quantum dots.

Response to Frequency Shifted Artificial Echoes in the Bat Rhinolophus ferrumequinum [PDF]
, 1974 In 5 roosting bats the resting frequency, that is the mean frequency of the cf-portion of consecutive sounds, is kept constant with a standard deviation which varies between 30 120 Hz in different bats and at different days. In 15 bats the emitted sounds

Doppler Shift Tolerance of Typical Pseudorandom Binary Sequences in PMCW Radar
Sensors, 2022 In the context of all-digital radar systems, phase-modulated continuous wave (PMCW) based on pseudorandom binary sequences (PRBSs) appears to be a prominent candidate modulation scheme for applications such as autonomous driving.
