Unter Software Defined Radio (SDR) fasst man Konzepte für Hochfrequenz-Sender und -Empfänger zusammen, bei denen kleinere oder größere Anteile der Signalverarbeitung mit Software verwirklicht werden. Die Analogkomponente kann ein Geradeausempfänger oder ein Überlagerungsempfänger (Superhet) sein. Vor allem Selektion und Modulation/Demodulation werden bei einem SDR mittels digitaler ... Prior government software defined radio approaches were inflexible, complex, and costly. In contrast, commercial wireless technology surged ahead with affordable innovations due to new mixed-signal Radio Frequency (RF) chips, high speed analog to digital (A/D) and digital to analog (D/A) converters, computer-aided code generation tools, and open source software such as Gnu Radio. All about software defined Radio (SDR) The hardware currently supported by SDR Console is shown in the table below. Software-Defined Radio (SDR) is a new technology that offers a simple alternative to bulkier analog radio, adding more flexibility, performance and a smaller form factor. SDRs are everywhere nowadays, from your cell phone to your wireless headset and your cable modem. List of software-defined radios. Jump to navigation Jump to search. This article provides a list of commercially available software-defined radio receivers. Name Type Frequency range Max bandwidth RX ADC bits TX DAC bits TX capable Sampling rate Frequency accuracy ppm Panadapters / Receivers ... Software Defined Radio attempts to place much or most of the complex signal handling involved in communications receivers and transmitters into the digital (DSP) style. In its purest form, and SDR receiver might consist simply of an analog-to-digital convert chip connected to an antenna. RTL-SDR (RTL2832U) and software defined radio news and projects. Also featuring Airspy, HackRF, FCD, SDRplay and more. Depending on the hardware used, its radio frequency coverage could span between 50 MHz and 2.2 GHz. Turn your mobile phone or tablet into an affordable and portable software defined radio scanner. SDR Touch currently demodulates WFM, AM, NFM, USB, LSB, DSB, CWU and CLW signals. You need. USB digital TV (DVB-T) dongle with the RTL2832U chip. Software Defined Radio-ontvanger De dagen dat je meteoren met grote complexe radio-ontvangers en antennes moest waarnemen, lijken voorbij. De ontwikkeling van goedkope RTL-SDR dongles maakt het mogelijk om in een handomdraai van je laptop een breedbandige radio-ontvanger te maken waarmee je radioreflecties van meteoren kunt detecteren. Software Defined Radios (SDRs) are constantly evolving. It seems like "the latest and greatest" SDRs are always popping up somewhere with today's rapidly growing technology.We thought ...

OMSCHRIJVING

De ontwikkeling van de kortegolf-ontvangsttechniek staat niet stil. In mei 2007 presenteerde Elektro de 'Software Defined Radio met USB-interfac'. Het doel van dit project was een zo eenvoudig mogelijke ontvanger die dankzij toepassing van geschikte software prima ontvangstresultaten levert. De benodigde programmatuur is via de Elektor-website en elders op het internet gratis verkrijgbaar. Al na enkele maanden kon deze ontvanger zich in een grote schare enthousiaste gebruikers verheugen. Het project wordt door talrijke softwareontwikkelaars ondersteund. Gebruiksaanwijzingen, uitbreidingen alsmede tips en trucs kunnen ook op het internet worden gevonden.
