  Integrated Kerr micro-combs, a powerful source of many wavelengths for
photonic RF and microwave signal processing, are particularly useful for
transversal filter systems. They have many advantages including a compact
footprint, high versatility, large numbers of wavelengths, and wide bandwidths.
We review recent progress on photonic RF and microwave high bandwidth temporal
signal processing based on Kerr micro-combs with spacings from 49-200GHz. We
cover integral and fractional Hilbert transforms, differentiators as well as
integrators. The potential of optical micro-combs for RF photonic applications
in functionality and ability to realize integrated solutions is also discussed.
