FM Transmitter circuit without Inductor In this tutorial we are going to construct an Arduino FM Receiver, and add it to our project arsenal. We will use the RDA5807 FM Receiver IC with Arduino and program it so, play any FM radio station which can be tuned by the user with a potentio...
Modulator: used for signal modulation. It encodes the signal in a certain way to meet communication channel requirements. It serves as an "up-converter" in a transmitter, in which it combines a low-frequency analog signal with the local oscillator signal to generate an RF signal. Demodulator: ...
Furthermore, this invention relates to a radio communication system, a receiver, a receiving method, a transmitter, a transmitting method, and a device for and a method of calculating delay times to perform multi-carrier transmission by providing guard interval periods, which do not raise the ...
transmitted data (e.g., the payload) may then be transmitted and received based on the synchronization, with optional “pilot” sequences dispersed throughout the payload to ensure that the transmitter and receiver remain synchronized (e.g., due to environmental changes, movement of the devices,...

avoid interference with adjacent channels. The tightness of bandwidth limitations plays a dominant role in the evaluation and selection ofmodulation technique. It also influences the design of transmitter and receiver elements, particularly the filters which can greatly affect the cost of a mobile ...
In terms of radiophysics, one may represent it like a parametric impact on the system consisting of a transmitter, receiver, and propagated wave. Hence the hypothesis presuming the existence of the Faraday phenomenon at radio frequencies looks plausible enough. In the present work, we propose a ...
Additionally, the distance of the signal transmission between the transmitter and receiver is directly proportional to the output power level, meaning that a higher output power level results in an extended transmission distance. An example of this concept is observed in Bluetooth technology, where a...
to build a narrowband SDR. Using a Linux-based computer, an RF front end, and an analog-to-digital converter (ADC), one can build a software-defined receiver. By adding a digital-to-analog converter (DAC) and possibly a power amplifier, one can build a software-defined transmitter[25]....
Therefore, each connection of the transmitter and receiver in Figure 7 (dashed lines) is called the projection angle, and based on its analysis at rest, i.e., without interrupting the field of view of a given pair of devices, it is possible to determine whether something interrupts the “...
