Correcting distortion in audio amplifiers is relatively easy – apply negative feedback (notwithstanding the objections from a sizeable number of audiophiles who hate negative feedback, but we are not ...
The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
In a new episode of Elektor Engineering Insights, Elektor contributor Roberto Armani demonstrates practical methods for audio ...
Based on Analog Device’s AD9858 1-GHz DDS (direct-digital-synthesizer), the Model LPO400A locking programmable oscillator generates a noise sine wave of 200 kHz to 400 MHz and ECL-level clock outputs.
A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive ...
How to measure linearity of an ADC using sine-wave input. How do non-idealities of a sine wave affect ADC linearity while testing it. Testing an ADC’s linearity. To obtain the transfer function of an ...
