The process of varying the AMPLITUDE of a sound, often periodically. An example of AM is the violinist's TREMOLO, where the amplitude of the vibrating string is rapidly altered by a movement of the ...

Keysight Technologies, Inc. (NYSE: KEYS) today introduced measurement capability designed to help engineers quickly and accurately characterize PAM-4 (pulse amplitude modulation with four amplitude ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

As a next-generation optical archive storage device for 8K video, we have been researching and developing holographic memory. Recent studies have focused on multi-level code instead of binary code to ...

Keysight Technologies, Inc. introduced measurement software designed to help engineers quickly and accurately characterize PAM-4 (pulse amplitude modulation with four amplitude levels) signals using ...

The process of varying the amplitude of a sound, often periodically. An example of AM is the violinist's tremolo, where the amplitude of the vibrating string is rapidly altered by a movement of the ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...
