We straddle two realms, analog and digital. The output of a sensor, musical instrument, the human voice, and most of the signals that originate in the real world are analog. Today most information processing is digital. This works well in terms of audio and video quality, but analog data must be converted by an analog-to-digital converter (ADC) […]
FAQ
Starting out with Verilog
If you are from a software background coming into digital design using CPLD/FPGAs (complex programmable logic devices/field programmable gate arrays) then you need to adopt a different way of thinking for designing logic. While Verilog and VHDL look like a conventional programming language, the way it is interpreted is different. With software for a microprocessor […]
Metrics to consider when choosing a PAN or WAN interface for telehealth applications
Telehealth is becoming a new way of helping people achieve a better quality of life, but the proliferation of wireless technologies has also introduced a personal health and medical device interoperability challenge that has not been seen before. The challenge rests in the need to have several wirelessly equipped devices and end equipments communicate adequately […]
Direct RF sampling with high performance ADC
by Philip Pratt, Texas Instruments Previously analog-to-digital converters (ADC) at high input frequencies were limited in usefulness due to distortion and noise performance. Today, however, ADCs can provide nearly 9.5 bits of effective number of bits (ENOB) at radio frequencies (RF) of 1 GHz with signal bandwidths greater than 200MHz. Such performance at high frequencies eliminates […]
