Digital Signal Processing and Software Defined Radio: Theory and Construction of the T41-EP Software Defined Transceiver by Albert F Peter AC8GY

This book combines Digital Signal Processing (DSP) and Software Defined Radio (SDR) principles into a single, easy-to-read, book. The book discusses various DSP principles, explains their purpose and how they work. It then discusses circuit(s) that can be used to implement the DSP principle. However, the book is unique in that is proceeds to use those design principles and circuits to develop an actual circuit that you can build and use to build the T41-EP (as seen of the cover); a 20W, HF, 7 band, CW/SSB Software Defined Transceiver (SDT) with features not even found in commercial radios costing five times as much (e.g., up to 192kHz spectrum display bandwidth, ALP CW decoder, Bode Plots, Bearing headings). The T41-EP is a self-contain SDT that does not require an external PC, laptop, or tablet to use. The EP stands for Experimenter's Platform because the T41-EP is designed around 5 small printed circuit boards. You can easily swap our PCBs for boards of you own design if you wish. The small board sizes (less than 100x100mm) allow you to take advantage of the special prices offered by most PCB fabricators. Because the T41-EP project is completely Open Source, you have complete access to the C source code that controls the T41-EP as well as the hardware schematics and Gerber files (for making your own PCBs). The latest (V12) PCBs are available for less than $5 each on the web site (https://groups.io/g/SoftwareControlledHamRadio). If you wish, pre-fabricated PCBs with all SMD devices already on the boards are available as a semi-kit from AI6YM (see https://ai6ym.radio/ for details).
