The DX7 runs on a Hitachi HD63B03RP CPU. Among other things, the DX7's firmware is responsible for handling user input, MIDI I/O, and processing the synth's LFO, pitch, and operator amplitude ...
Abstract: In this paper, we investigate the impacts of transmitter and receiver windows on the performance of orthogonal time-frequency space (OTFS) modulation and propose window designs to improve ...
We present the first all-digital PLL and polar transmitter for mobile phones. They are part of a single-chip GSM/EDGE transceiver SoC fabricated in a 90 nm digital CMOS process. The circuits are ...
