In one embodiment, a digital input signal having undesired image spectra is input to two paths. In one path, the digital input signal is phase shifted so that an output of each path are out of phase by substantially 180 degrees at a frequency of the undesired image spectra, so that the undesired image spectra are substantially suppressed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication signal image suppression for multi-frequency operation","description":"A method and system for image suppression and digital-to-analog conversion (DAC) of a radio frequency (RF) signal is disclosed.
