In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

From its early applications in the 1960s for T1 communications services, multilevel signaling has played an important role in ... pulse amplitude modulation (PAM5) enables Gigabit Ethernet (GbE) 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 ...

Most high-throughput data networks rely on optical transmission methods to transfer data, with two dominant modulation techniques: 4-level pulse amplitude modulation (PAM4) and coherent modulation.

Pulse amplitude modulation (PAM) is a way to pack more bits into the same amount of time on a serial channel. The usual mechanism used in serial communications is the binary non-return to zero (NRZ).

The MBC-AN is designed for analogue applications where a high purity carrier is required. They are easy to implement, and fully automated with their auto-set function. The MBC-DG-LAB controller can be ...

New research published in Current Biology has found that cyanobacteria use variations in the amplitude (strength) of a pulse to convey information in single cells. The finding sheds light on how ...
