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 ...
The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...
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 ...
