In the first installment of this course, we learned that a digital value is a quantity that varies “in steps” and can take on only a finite number of values. In today’s logic systems, only two ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...

In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Three ...

Every modern computer has a microprocessor in it, but not many have a digital signal processor (DSP). Since the CPU is a digital device, it clearly processes digital data, so you might wonder what the ...

Confused by analog-to-digital converter specifications? Here's a primer to help you decipher them and make the right decisions for your project. Although manufacturers use common terms to describe ...

Differences between digital and analog triggering. Advantages of digital triggering. How to tell what type of triggering is used by an oscilloscope. An oscilloscope’s trigger function, which ...

Digital video is a method of representing the infinite variations of video signal levels inside a specified limit (e.g. 0mV to 700mV) as a limited number of binary numbers. Figure 1 shows a simplified ...
