If you find yourself in the middle of a portrait session, it can feel like you don’t have time to dial in your settings. But DeFranco encourages photographers to overcome the impulse to rush. “Take time to stop and look at what you’re doing.” Taking a few extra seconds in the ...
Signal processing is used in order to analyse measured data. Read the article to learn how signal processing is performed and applied in DAQ applications.
Data processing is the first step. It includes data preprocessing and augmentation techniques such as speed/time/noise/impulse perturbation and time stretch augmentation, fast Fourier Transformations (FFT) using windowing, and normalization techniques. For example, in Figure 2, the mel spectrogram is g...
In digital signal processing, an FIR is a filter whose impulse response is of finite period, as a result of it settles to zero in finite time. This is often in distinction to IIR filters, which can have internal feedback and will still respond indefinitely. The impulse response of an Nth...
(Image credit: Shutterstock / NicoElNino) The core concepts of AI Yes, AI is everywhere - but what makes it work? Whether it’s machine learning, deep learning, or natural language processing, these core concepts are the backbone of modern AI. Let’s dive into the magic behind the machin...
The impulse response of the entire transmission system, including the equalization, is directly evaluated from the perspective of time response, ensuring that there is no inter-symbol interference. The Nyquist shaping theorem is met by the frequency domain equalization, and the condition of no inter...
The mechanism of memory remains one of the great unsolved problems of biology. Grappling with the question more than a hundred years ago, the German zoologist Richard Semon formulated the concept of the engram, lasting connections in the brain that resul
If, however, they miss each other in time, so that the effect of the first impulse has decayed before the second arrives, they might both fail to fire the target neuron. Thus, neurons act as coincidence detectors and do evaluate signal correlations (1, 23). The exact details of this ...
