This 3 part series will get you quickly up to speed on sampling theory, how undersampling works, how sampling is implemented in test equipment. Then, we utilize our sampling knowledge and apply it to real and complex FFTs. We'll show you some test time saving tricks that can be applied to complex signals to get at IQ impairements.

Below are the descriptions for each of the lessons included in the series:
-
Introduction to Low Pass and Band Pass Sampling
WSOCT and SavvyPaper introduce you to low pass and band pass sampling from a test perspective. Topics include: Nyquist, aliasing, filtering and undersampling. We use NI Labview software as a tutorial aid.
-
FFT - Getting Started with Real Signals (English)
WSOCT and SavvyPaper teach you about FFTs and real signals. Topics include FFT, gaussian noise, noise effects on FFT and noise floor, spurs, coherency and non-coherency. We use NI Labview software as a teaching aid.
-
FFT - Getting Started with Complex Signals
WSOCT and SavvyPaper teach you all about the complex FFT. M number of cycles, phase imbalance, complex to real signals, small phase imbalances, amplitude imbalance. We use NI Labview software as a teaching aid.
