Signal to Noise (Sinclair novel)

Signal to Noise (ISBN 978-0062515346) is a 1997 cyberpunk novel by Carla Sinclair published by Harper. This is the author's first novel; she had previously written non-fiction works. It is set in San Francisco. Tiffany Lee Brown, writing in Wired magazine, stated that the "cybercultural parody" reflects "distinctive perspective on the foibles of the wired life" and "caricatures" people in the San Francisco technology environment.

According to the author she took seven months to create the initial draft before selling it to the publisher, which asked for a substantial rewrite within a two-month period; the publishers stated a dislike of the, in Sinclair's words, "too clichéd" criminal characters. Sinclair stated that the rewrite affected about 66% of the book. She did the rewrite during a pregnancy. Sinclair stated that she included elements she noticed in real life and that she "enjoyed" writing scenes portraying violence, citing an increase in adrenaline, rather than having them make her anxious.
