Digital Signal Processing (DSP):In digital systems, DSP algorithms can be used to reduce spurious components. Noise Reduction:Reducing noise sources and employing noise-reduction techniques can improve SFDR. Spurious Free Dynamic Range (SFDR) is a critical parameter that defines the purity of signals...
1 Adaptive spectral tuning will continue to shift from the RF to the digital signal processing realm. This sea change in wideband RF sensing will enable size, weight, power, and cost (SWaP-C) benefits: higher receive and transmit channel counts at lower cost per channel, in the same or...
Introducing additional SFDR phase optimization terms, the desired signal’s phase per element after the array calibration and SFDR optimization steps can be written as:Similarly, this SFDR phase optimization step results in an output phase per element for the 2IF spur that can be written as:...
