Measurement of Power Spectra from the Point of View of Communications Engineering - R. B. Bl... Book

I find myself in the difficult (embarrassing) position of hoping for a sign from a recently deceased family member. This book contains a lot of interesting anecdotes about people who claim to have received such signs. This is not one of those crazy new age books that borders on ridiculous; the stories are actually compelling and in many cases corroborated by outside evidence. I am no more sure that a sign is forthcoming, but the book was definitely interesting and worth reading.
