Nebeker: Let's start with your background, where and when you were born, and a little about your family. Liu: I was born in Shanghai, 1934, before the Second World War. We moved away from the coastal provinces to the inland step-by-step as the battle front was getter closer and closer. After the war, we returned to Shanghai. Then in ‘49 my parents ...
Nebeker: You had a bachelor’s degree in hand? Liu: Yes. Most of my classmates came here as students, but I came as an immigrant. That means I had to register at the draft board and be classified as 1-A and go through all that. I started working at Western Electric. Nebeker: While you were a student? Liu: Yes. Let me go back. I arrived here in New Y...
Liu: As a teaching fellow, I had to teach I believe a five credit, sophomore circuit course. I was paid $550 for a semester. I got my master’s in ‘56. My father and I got the degree at the same time; I think it was the first [time] that happened in the history of the college. We got our picture in the paper and all that. It was the 102nd or 101st c...
Liu: I applied for and was fortunate enough to be given a Bell Laboratoriesfellowship. That was to begin in September 1957. The summer of 1957 before I started my fellowship I had a summer job at Bell Labs, Murray Hill. Nebeker: What were you doing there? Liu: What was called a transversal filter, using transmission lines. Nebeker: What was the app...
Liu: I finished my thesis in December of ‘59. Nebeker: Your degree was granted then in 1960? Liu: Yes. Poly grants degrees once a year. I was cutting it quite close because my fellowship ran out after two years. I was married and a child was on the way. I had to pass my language examination. We had only one language requirement, so I studied French...
Nebeker: What was your initial assignment at Bell Labs? Liu: I have to think. The department I joined used to be called the Exploratory Development Department—halfway between research and development. It was concerned with transmission circuits. At that time, there needed to be some planning for the demand for communication channels. The conclusion...
Nebeker: Did you like those years at Bell Labs? Liu: I liked it very much in the sense that it helped me to mature, but I don’t think Bell liked me because I did very little for them. I remember a supervisor that I had, he was a little older and gave me good advice—that one has to deal with the real world. If something has to be done, somebody in t...
Nebeker: What happened after three years? Liu: I was fortunate to receive an offer to come here to Princeton and teach; that was in September of ‘62. I guess the three years at Bell Labs really helped me to grow up. I was able to take responsibility much better. Took a cut in salary, but I have enjoyed every minute of it. Nebeker: Tell me about you...
Liu: During the summer of 1966, there was a COSINE Committee meeting at Princeton. The COSINE Committee is an NSF committee. Mac Van Valkenburg was very active at NSF doing things of this sort, and I was involved in various decisions. Most of the things went way above my head. A colleague of mine said, “Bede, at night we have a discussion group on ...
Liu: Audio File 1. MP3 Audio (333 - liu - clip 4.mp3) In 1967 or so, I proposed to NASA a way to implement digital filters using delta modulation, without the multiplier. In delta modulation, it is easy to do multiplication by one bit. That was not funded. But, two or three years later, I was working with Abe Peled and I asked him to look at it aga...
Biography. Bede Liu’s pioneering work on signal processing focused primarily on lowering implementation complexity and reducing power consumption, which have been central to the creation of cost-effective, high performance, low-power signal processing, important in the development of mobile and multimedia systems.
Bede Liu went through 5 elementary schools and 7 middle schools (names upon request) before settling down at the Taiwan University, where he lasted full four years. He didn't quite make the University's varsity swimming team. He was, however, a member of the BTU-U team-of-four that took the championship at the First Taipei Open Bridge Tournament.
