Receiver Dynamic Range - Part 2

Author: 

Robert E. Watson

This Watkins Johnson app note describes dynamic range measurements on receivers. Part 2 discusses "comprehensive measurements," or figures of merit that combine the primary measurements, such as noise figure or IP3, to provide a picture of the range of power levels that a receiver can handle. The app note is hosted on RF Café.

Rick Lyons on Using the Forward FFT Algorithm to Compute the IFFT

Submitted by rfrobenius on

Instructor Rick Lyons has written a new post on his blog at DSP Related discussing ways that you can use an FFT algorithm to compute the IFFT.

If you need to compute inverse fast Fourier transforms (inverse FFTs) but you only have forward FFT software (or forward FFT FPGA cores) available to you, below are four ways to solve your problem.
