Superheterodyne receiver - Wikipedia, the free encyclopedia In electronics, a superheterodyne receiver (often shortened to superhet) uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. It was i
Measurements on RTL-SDR E4000 and R820T DVB-T Dongles: Image Rejection, Internal Signals, Sensitivit Over on the SDRSharp Yahoo group, HB9AJG has posted an interesting report in a PDF file containing some measurements (Note you will need to be a member of the group to download the file titled “Some Measurements on E4000 and R820 Tuners.pdf”. Here is a Di
Airliners.net Reject Reasons It's a common fault to try and save blurry images by sharpening. This will then result in an over-sharpened rejection. Again we stress that you look carefully at the original image and check if it's in focus. If it is, then the blurry rejection may have b
