In analog design, circuit stimulus is treated as a continuously varying signal over time. The behavior of the circuit is modeled in the time and frequency domains with attention focused on the fidelity/precision, consistency, and performance of the resultant waveforms. Circuit variability, both manuf...
But analog audio is known for its imperfections, and when real circuits handle real waveforms, theory doesn’t easily match practice. A piece of equipment could distort in any way. More likely, your waveform will be recreated but not properly; or perhaps distortion is only experienced on one ...
These electrical quantities may appear as fast or slow “DC” continuous direct measurements of a phenomenon in the time domain, as modulated AC waveforms (using a wide variety of modulation techniques), or in some combination, with a spatial configuration of related variables to represent shaft ...
And by this I mean one could see how close the analog signal comes to its intended waveform. There inevitably will be some deviation between the virtual and actual waveforms, in the same way that tolerances describe the deviation of machined parts from their intended dimensions. Could the analys...
Digital filtering of averaged evoked potential waveforms by microprocessor is presented and evaluated as a technique for enhancement of signal-to-noise ratio, and compared to analog filtering. It is shown that analog filters inherently produce distortions of amplitude and phase, and that these ...
Analog design and verification is something I know almost nothing about, bit it seems to include simulation and a lot of inspection of waveforms. This has lead to a flow where each engineer sits at the screen, simulates, inspects, and iterates until he is happy with the design....
The AD9914 uses advanced DDS technology, supports a user defined linear sweep mode of operation for coupled with an internal high speed, high performance DAC generating linear swept waveforms of frequency, phase, or to form a digitally programmable, complete high frequency amplitude. A high speed,...
waveforms. Triggering options provided by the oscilloscope includes source, level slope, pre-trigger and post-trigger. These options are the same for all oscilloscopes, but varies in the manufacturer’s provision in advanced triggering functions. These advanced options can be utilized according to the...
peripatitis wrote:band limited oscillators? they can't even get simple waveforms to not sound muffled, etc. I disagree with this too. There are bad digital oscillators and filters, but there are also excellent ones that would pass any A-B test. ...
Before the FMCW data can be processed and the useful target information deduced, the downconverted baseband waveforms must first be filtered and sampled using an analog front end (AFE) and ADC, respectively. Outside of the usual ADC considerations such as the number of channels, dynamic range,...
