- 17:52, 18 May 2024 B200-B205mini FM Receiver (hist | edit) [6,000 bytes] Wavewalkerdsp (talk | contribs) (Created page with "B200B/B205mini FM Receiver This tutorial describes how to receive broadcast commercial radio stations transmitting Frequency Modulated (FM) signals using the Ettus Research B200/B205 mini receiver. The following hardware is needed for this tutorial: * B200/B205mini Receiver * VHF Antenna It is likely (but not guaranteed) that the Ettus Research B210/B200 will also work for this tutorial with no other modifications. Please connect the antenna to the B200/B205mini, and...")

Before continuing it is useful to refer to the tutorial Signal Data Types which describes different data types in GNU Radio. ==Data File Formats== Each binary file will have a specific data format, with the two most common being 32-bit floats and 16-bit integers. RF samples can be both positive and negative, and therefore all integers will be implied to be signed integers, for simplicity. The binar...")

'''Virtual Sinks and Virtual Sources''' are blocks which can be used to simplify the look of a flowgraph. ==Connecting Virtual Sinks and Sources== Initially when virtual sinks and sources are added to a flowgraph they are given a white color, which represents that they do not have a data type yet. The data type will be assumed when connected to a block. File:Virtual_sink_source_...")

Equivalently, it can be stated that frequency shifting is the process of changing the center frequency of a signal. Frequency shifted can be implemented many different ways, although this tutorial will focus on the simple method of multiplication...")
