Unfortunately, a von Neumann machine is really pretty inefficient at this type of calculation so the Harvard architecture lives on in many DSP chips meaning that a multiply and add operation can be performed in one clock cycle; this composite operation being termed a Multiply ACcumulate (MAC) fun...
The Russian word for node—uzel—also has the meaning of knot. In topology a knot is, in the simplest case, a continuous closed space curve that does not intersect itself. Node in physics, a point or surface in a standing-wave system at which the kinetic or potential energy of the wav...
The result is a linear phase response, meaning that the passing waveforms will be minimally distorted. It is often used in audio crossover systems. Analog Bessel filters are characterized by almost constant group delay across the entire passband, thus preserving the wave shape of filtered signals ...
6a. The circulator is implemented in a ferrite material; passive filtering is done with piezoelectric acoustic wave technology; and the power amplifier (PA), low noise amplifier (LNA), local oscillator (LO), and mixer are implemented with CMOS and compound semiconductor electronics. Many modern ...
to adapt to statistical variations of the unknown channel. According to the LMS criterion, the updated tap-weight vector\(\hat{{{\bf{w}}}({{{\bf{n}}}+{{{\bf{1}}})\)is optimal in the meaning of mean square error40, and the updating rule is $$\hat{{{\bf{w}}}({{{\bf{n...
In theory, the perfect TTL on/off signal would be 0V representing OFF (meaning a digital value of 0), and 5V representing ON (meaning the digital value of 1). However in practice, it is nearly impossible to achieve such precision, so the acceptable ranges have become 0 to 0.8V for ...
A method of compressing and decompressing a sequence of images comprises segmenting a first and second image (30, 32) into regions (35a, b, 37a, b) of pixel locations. For each of a plurality of the r
Among the terms used in the disclosure, terms defined in a general dictionary may be interpreted with the same or similar meaning as the meaning in the context of the related art, and unless explicitly defined in the disclosure, it is not to be construed in an ideal or overly formal sense...
In some experiments, multielectrode extracellular electrophysiology was also performed by utilizing either a 60 or a 120 channel MEA system (Multichannel Systems Gmbh, Germany) that allowed for recording simultaneously from many RGCs. Analyses were performed offline using Spike 2 (Cambridge Electronics ...
