Jeannine Henaff facts for kids

Jeannine Henaff (born 7 August 1936) is a French electrical engineer. She is known for her important work with surface acoustic waves. These waves are used in electronics, especially for things like videotelephony, which is like video calls.

Early Life and Education

Jeannine Henaff was born in Paris, France, on August 7, 1936. She loved learning about how things work.

She decided to study engineering. She went to a special school called the École supérieure d'électricité. This school is often just called Supélec.

After her studies, she earned a high degree in physical sciences. This means she became an expert in how the physical world works.

A Career in Telecommunications

In 1958, Jeannine Henaff started working at a place called the Centre national d'études des télécommunications (CNET). This center was very important for developing new ways to communicate.

She focused on using surface acoustic waves in electronics. These waves are tiny vibrations that travel along the surface of a material. They can be used to process electronic signals.

One of her key ideas was using special filters, called SAW filters. These filters helped with complex calculations needed for video calls. This made it easier to send video and sound over long distances.

Books and Awards

Jeannine Henaff also shared her knowledge with others. She wrote a book with Michel Feldmann. The book was called Traitement du signal par ondes élastiques de surface in French.

Later, this book was translated into English. Its English title is Surface Acoustic Waves for Signal Processing. It helped many engineers learn about this field.

In 1997, Jeannine Henaff received a big honor. She was named a Fellow of the IEEE. This award is given to engineers who have made major contributions. She earned it for her work in designing and building telecommunication systems.
