1. Three basic digital modulation formats are still very popular with low-data-rate short-range wireless applications: amplitude shift keying (a), on-off keying (b), and frequency shift keying (c).

Keysight Technologies, Inc. introduces Quantum Circuit Simulation (Quantum Ckt Sim), an innovative circuit design environment that speeds up the development of intricate quantum circuits.

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

The IC design engineers at Rohde & Schwarz make extensive use of an Accelerated Parallel Simulator (Virtuoso-APS) package to efficiently perform the complex simulations required to meet the demanding ...

John R. Carson has been inducted into the Electronic Design Hall of Fame for his contribution to radio modulation innovations. This year, we recognize John R. Carson for two major contributions to ...

A representative view of binary modulation and a third state for ternary modulation is shown in Figure 3. Figure 3: Left: Binary Modulation where one side is of the H-bridge is ON (red current flow).

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all rad… ...

Abstract. Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare ...

Keysight's PathWave ADS RFPro integrated 3DEM Simulation enables interactive 3DEM-circuit co-simulation of any selected layout and components without modifications to layout or design.

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or ...

Carrier frequency: In PWM-based VFDs, the rate at which output transistors are gated or turned on, usually 2 to 15 kHz. ( See image .) Higher values yield better current waveform, but more VFD losses.
