Why Digital Oscilloscopes Appear Noisy

Why do digital oscilloscopes appear noisier than traditional analog oscilloscopes? In EEVblog #601 – Why Digital Oscilloscopes Appear Noisy posting Dave busts the myth that digital scopes are noiser than analog scopes, and demonstrates what inherent advantages digital scopes can have over analog scopes in terms of true waveform capture. And how long exposure camera shots

Introduction to Hearing Aids

Introduction to Hearing Aids is a good introduction to technology inside hearing aids.  The two basic types of technology for hearing aids are analog and digital. Analog hearing aids process electrical sound in the analog domain; the more recent digital hearing aids process electrical sound in the digital domain. The earliest analog hearing aids simply

FPGA boards under $100

Nowadays you can find many low-cost microcontroller devboards (starting from just few dollars/euros). More recently, we’ve seen ARM Cortex kits for $10-$50, the flowering of the whole Arduino ecosystem, and of course, the Raspberry Pi. It’s microcontroller heaven with very many dev boards available. You you want more performance, there is a wide selection of
