Digital receivers have revolutionized electronic systems for a variety of applications including communications, data acquisition, and signal processing. This series shows how digital receivers, the ...

Over-the-air (OTA) broadcast television may be making a comeback with major networks now sending HDTV signals capable of being picked up by the humble rooftop antenna. But subscriber TV services from ...

Let’s face it: analog-to-digital converters (ADCs) operate differently. Their analog inputs are voltage-input-sensitive devices that leave radio-frequency (RF) engineers scratching their heads about ...

Wireless receiver sensitivity will benefit from using high gain low noise amplifiers made possible by the high input mixer, writes Richard Wilson Linear Technology has introduced an active ...

Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...

Add articles to your saved list and come back to them any time. UPDATE: Since I wrote this post a few boxes with RF Modulators have come to my attention. One is the Altech UEC DT3900RF, although it's ...

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage – from design and prototyping to maintenance in the ...
