subroutine timf2(x0,k,nfft,nwindow,nb,peaklimit,x1, &
slimit,lstrong,px,nzap)
! Sequential processing of time-domain I/Q data, using Linrad-like
! "first FFT" and "first backward FFT", treating frequencies with
! strong signals differently. Noise blanking is applied to weak
! signals only.
! x0 - real input data
! nfft - length of FFTs
! nwindow - 0 for no window, 2 for sin^2 window
! x1 - real output data
! Non-windowed processing means no overlap, so kstep=nfft.
! Sin^2 window has 50% overlap, kstep=nfft/2.
! Frequencies with strong signals are identified and separated. Back
! transforms are done separately for weak and strong signals, so that
! noise blanking can be applied to the weak-signal portion. Strong and
! weak are finally re-combined, in the time domain.
