It's no news that digital RF receivers are revolutionizing applications in everything from cellphones and communications receivers, to radio direction finding, to data acquisition and signal processing. But, there are still EEs not familiar with digital receiver architectures, and their hardware and software.
As such, Pentek, a maker of DSP and data acquisition boards, is now offering a free handbook---in its 4th edition---that can help you better understand digital receivers.
Tutorials and Products
Although about half of Pentek's notes focus on the company's products (which include multi-channel digital receivers and digital up-converters), the handbook is still quite tutorial in nature, explaining how digital receivers work as fundamental building blocks in software defined radios, or SDRs.

Pentek explains how SDRs can replace conventional analog receiver designs---while significantly bettering an analog design's performance, density, and cost. The inner workings of digital receivers are explored in these notes, with an in-depth description of internal structures and devices. The book is well illustrated, too.
In addition, the use of FPGAs is discussed. FPGAs are what make SDRs definable.
