A previous article suggests that most digital output waveforms follow a nearly Gaussian profile ( Reference 1 ). Let’s test that theory. Figure 1 depicts the rising edge from a Texas Instruments DL100-44T LVDS ...

Which step in Figure 1 best approximates the digital signals you work with every day? The piecewise-linear step starts with a jerk, mindlessly follows a perfectly uniform ramp, and smacks hard into its upper limit. Real signals don’t do that. ...

Digital potentiometers (“Dpots”) are a diverse and useful category of digital/analog components with up to a 10-bit resolution, element resistance from 1k to 1M, and voltage capability up to and beyond 15v. However, most are limited to ...

Digital gates are fundamentally analog in nature. They use transistors. Sure, these transistors are operated at their conduction extremes (which is why they are called “digital”), but during the logic state transition they're pure ...

Shyam Sunder Tiwari Electronic Design Designers seeking a quick and easy frequency source often use a relaxation oscillator (Fig. 1) based on digital gates such as the 74HC14 inverter with hysteresis. The oscillator is also useful in sensor signal ...
