Fig.1: NRZ signal (top) and eye diagram (bottom). Pulse amplitude modulation builds upon this concept by encoding data across multiple voltage levels. PAM4 uses four levels. A PAM4 signal can appear ...

Multilevel inverters have become a suitable candidate for high power applications due to their output performance and power density. In particular, Four-level neutral-point-clamped inverter (NPC) has ...

Result: The experiment on Pulse Position Modulation (PPM) achieved successful generation and transmission of PPM signals. The signals were transmitted over a wireless communication channel and ...

This paper presents the implementation of an 8-channel Pulse Width Modulation (PWM) block using Hardware Description Language (HDL) which is controlled by an AXI4-Lite interface. The block was ...
