Digital Signal Processor: How Gene Frantz Invented DSP technology?

In the 1970s, a group of engineers at Texas Instruments, including Gene Frantz, developed the TMS5100, a chip featuring digital signal processing (DSP) technology for speech synthesis. This chip powered the educational toy, Speak & Spell, which became a paradigm shift in the consumer electronics industry. DSP technology was used in myriad applications, and Texas Instruments changed its marketing approach and partnered with universities to create textbooks and more engineers with DSP knowledge. Today, DSP technology is a requirement for various technologies and the global market for DSPs is expected to reach $16 billion by 2027.
