But as [Alan] explains, the action of keying the transmitter imposes a low-frequency square wave on the carrier, so the occupied bandwidth of the signal depends on how fast the operator is sending ...

Whereas the differential threshold is the just noticeable difference (jnd) of a single frequency, the critical bandwidth represents the ear's resolving power for simultaneous tones or partials. In a ...

Plasmonic modulators are tiny components that convert electrical signals into optical signals in order to transport them ...

A modulator has now broken the terahertz mark. The ultrafast component efficiently transmits large volumes of data into the fiber-optic network in a short space of time.

Yokogawa Test and Measurement launched its latest family of differential probes that feature a maximum input voltage of 2,000 V and frequency bandwidth of up to 400 MHz. To measure everything from ...

The Anritsu MG3710E is a cost-effective vector signal generator with up to two RF ports in a single unit. Each port can output RF signals with a frequency range of 100kHz to 6GHz and a maximum ...
