Hilbert Transformer

A Hilbert transformer converts a real signal into a complex (analytic) signal by eliminating the negative frequency components. The difference between a Hilbert transformer and a Fs/4 downconverter is that both input and output of the Hilbert transformer are at baseband. There is no downconversion process.  Input signal must be band-limited to less than Fs/2.

Highlights:

  • Converts a real signal into complex (analytic) signal by eliminating negative frequency components
  • Input and output already at a baseband – no downconversion
  • Input signal must be band-limited to < Fs/2

epgHilbertDec2Path2

This incorporates a Hilbert transformer core. The complex output is in 2 paths (2 complex output samples per clock). With an inherent decimation of 2, then, an Fs of 4*Fclk is supported. For a clock rate of 250 MHz, this means a real input sample rate of 1 GS/s in 4 input paths becomes a complex output sample rate of 500 MHz in 2 paths operating at 250 MHz.

Highlights:

  • Decimation by 2 and complex output in 2 paths
    • Fs = 4*Fclk
