Line 15: ===DSP & Display stage=== Once the signal is digitized, it is separated into [[quadrature phase\|quadrature]] and in-phase components using a quadrature detector, which is typically implemented with a [[Hilbert transform#Discrete Hilbert ~~transforms~~transform\|discrete Hilbert transform]]. Several measurements are made and displayed using these signal components and various [[digital signal processing\|DSP]] processes, such as the ones below '''Signal Spectrum from FFT'''
