What's the Difference between the RS-232 and RS-485 Serial Interfaces?
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.
What’s The Difference Between Bit Rate And Baud Rate?
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.
How Do Operational Amplifiers Operate?
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.
Understanding Modern Digital Modulation Techniques
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.
Build Your Own Transformer
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.
What's the Difference between EPON and GPON Optical Fiber Networks?
Passive optical networks defined and explained. EPON and GPON are introduced and compared.
Back to Basics: Impedance Matching
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.
What's the Difference between a Dipole and a Ground Plane Antenna?
This article shows how a dipole and and ground plane antenna are similar but also different.
Select the Right Varistors for Overvoltage Circuit Protection
Though MOVs are relatively simple devices, choosing the right one requires some knowledge.
What's the Difference between IPv4 and IPv6?
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.
