A Novel Extra Low IF Receiver for the GSM Band Design How-To 12/20/2001 Post a comment Authors from the University of Athens, Greece, describe the design of an extra low IF (455 kHz) receiver topology for wireless systems. Overall receiver performance is evaluated in terms of noise figure, inter-modulation, blocking requirements, SNR, and C/I.
A Time-Domain-Based Technique for Noise Measurements News & Analysis 12/14/2001 Post a comment Although electronic noise is often a critical design parameter in an analog system, evaluation of noise performance of circuits that perform a frequency translation from RF to baseband is not easy to do. Torben Larsen and colleagues from Aalborg University in Denmark describe a time-domain-based technique to determine the noise factor of a device with a low desired output frequency.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
