Abstract: Digital receivers are a main subject that forms modern radio astronomical technology Because of advancements in analog-to digital converters (ADCs) and increases in digital signal processing capacity, massive amounts of astronomical data can be processed fast enough to match the scientific observation requirements So, in this chapter, we will introduce the core processing procedures in digital receivers to bridge analog RF to science processing data: digitization, channelization, and packeting Many other arithmetic operations can also be applied between or after these core procedures such as pulsar timing, dedispersion, beamforming, correlation, etc, which will be discussed in further chapters
