WebJan 19, 2024 · DFT or FFT algorithm can convert this time-domain discrete signal into a frequency-domain. FFT algorithm overview Simple Sine Wave to Understand FFT. To understand the output of FFT, let’s create a simple sine wave. The following piece of code creates a sine wave with a sampling rate = 100, amplitude = 1 and frequency = 3. Especially for advanced semiconductor technologies, it is expected some of the chips on each manufactured wafer contain defects that render them non-functional. The primary objective of testing is to find and separate those non-functional chips from the fully functional ones, meaning that one or more responses captured by the tester from a non-functional chip under test differ from the expected response. The percentage of chips that fail test, hence, should be closely rel… c in general education class
