The invention of the integrated circuit (IC) by Jack Kilby at Texas Instruments and Robert Noyce at Intel revolutionized the field of digital signal processing. This breakthrough led to smaller, more efficient electronic devices that could process and analyze signals in real-time, paving the way for advancements in telecommunications, audio technology, and much more.

Jack Kilby & Texas Instruments

Jack Kilby changed the world of engineering when he created the first integrated circuit (IC) at Texas Instruments. This tiny piece of technology made it possible for many parts to fit on one chip, instead of spreading them out over a large area.

Because of his work, electronic devices could become much smaller and more powerful. Think about how you can hold a super-smart phone in your hand! That’s partly thanks to Kilby’s big idea.

Texas Instruments saw this invention as really important and got behind it in a strong way. They knew that these new chips could do big jobs even though they were small in size. This helped shape digital signal processing by making room for new tools and machines that engineers use to work with signals like sound or radio waves.

Now, almost every gadget we use has some kind of IC inside, working hard to make everything run smoothly.

Robert Noyce & Intel

Robert Noyce helped change the world of electronics. With a group, he started Intel in 1968. This company became very big and important for computer chips. Noyce made the first chip that could do many things at once.

His work let people build smaller, powerful computers.

Intel grew fast because of his ideas and what is called Moore’s Law. Gordon Moore, another founder of Intel, said computer power would grow a lot every two years while costs stayed low.

This idea pushed engineers to make better tech over time. Now we see digital signal processing (DSP) everywhere – from phones to music players.

Gordon Moore & Moore’s Law

Gordon Moore is a big name in the world of tech. He helped start Intel, which is a huge company that makes computer parts. In 1965, he came up with a rule called Moore’s Law. It says that the number of tiny parts on a computer chip will double every two years.

This idea has been true for many years and made computers get better fast.

Because chips got more powerful without getting bigger, engineers could make amazing things for digital signal processing (DSP). The tools they use to work with sounds and pictures keep getting better because of this law.

Now let’s see how the birth of digital signal processing changed everything.
