WebbAnalog Embedded processing Semiconductor company TI.com Webb10 jan. 2015 · Blocking is defined as the degradation of receiver sensitivity, in the presence of a much stronger (blocking) signal. Therefore we must first understand that Sensitivity is the measure of what the smallest possible detectable signal is. Let's assume you have a radio receiver and you monitor a certain signal at an SNR of 6 dB. tawesco automotive s.r.o

"WebbA low IF receiver has the same structure with direct conversion receiver. The only change is that the IF is moved from DC to a lower frequency to avoid the drawbacks of working at DC, mainly the DC offset and 1/f noise from IQ demodulator. However, a low IF receiver typically has a much higher requirement for IRR (Image Rejection Ratio). This " - Receiver blocking 測試
