I have the following books on sale. The books are like new since I took great care of them. I did check up the used book prices at Amazon and am willing to offer an even lower price.

• $40, A wavelet tour of signal processing (The sparse way), 3rd edition, S. Mallat
• $30, An introduction to statistical signal processing, R. Gray and L. Davisson (EE quals related)
• $5, Learning OpenCV, G. Gradski and A. Kaehler
• $10, Microelectronic circuits, 5th edition, Sedra / Smith (EE quals related)
• $5, Beginning Ubuntu Linux, 4th edition, K. Thomas and A. Channelle
• $3, This time is different, eight centuries of financial folly, C. Reinhart & K. Rogoff (NY Times bestseller, not a textbook but great for those interested in finance)

Please contact me if interested. Thanks!
