Serial interfaces are used in most electronic equipment today. Some of the original serial interfaces like RS-232 and RS-485 are still widely used. This article summarizes these interfaces and shows where they are still used today.
Serial-data speed is usually stated in terms of bit rate. However, another oft-quoted measure of speed is baud rate. Though the two aren’t the same, similarities exist under some circumstances. This tutorial will make the difference clear.
Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds.
Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited spectrum available, the type of modulation is more critical than it has ever been.
When the right off-the-shelf part just can’t be found, you may want to consider designing a custom transformer to fit your specific requirements.
Passive optical networks defined and explained. EPON and GPON are introduced and compared.
The term “impedance matching” is rather straightforward. It’s simply defined as the process of making one impedance look like another. Frequently, it becomes necessary to match a load impedance to the source or internal impedance of a driving source.
This article shows how a dipole and and ground plane antenna are similar but also different.
Though MOVs are relatively simple devices, choosing the right one requires some knowledge.
If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out of addresses but have not fear, the Internet Engineering Task Force (IETF) is here with IPv6.
