    Glen Brisebois EDN I recently had the opportunity to investigate a new micropower 6-MHz LTC6255 op amp driving a 12-bit, 250k sample/sec LTC2361 ADC. I wanted to acquire the FFT of a pure sinusoid of about 5 kHz. The problem is that getting the FFT ...

  1. Moshe Gerstanhaber EDN The multivibrator is a common circuit that consists of an amplifier with both positive and negative feedback (Figure 1a). When the output is positive, the positive input terminal equals ½V+, and the voltage at the ...

  2. José M Miguel EDN Testing audio-noise-reduction circuits, PLLs (phase-locked loops), and audio-frequency filters may require a noisy sine wave, one that is summed with white noise. Using a typical computer sound card, free software, and an ...
