Hi, all,
I am reading "RF system design of transceivers" by Qizheng Gu.
When discussing the ADC dynamic range, he indicates the ratio of in-band noise to quantization noise should be considered in ADC's dynamic range, but I am confused how to decide/calculate the ratio?
In this book, the...
Hi all,
when considering the dynamic range of ADC, some margin for fading should be saved, but for different systems, how to decide the margin level?
For example, DVB-T system with OFDM, what's the margin should be saved?
For CDMA system, what's the margin?
Thanks!

Hi all,
How to use single-end port network analyzer to test balun---single end to differential ports?
I have tested three pieces of 2-port S-parameter with three different port loading separately, so there is a question, how to use these parameters to calculate the insert loss of balun?
Are...
DVB tuner?
There are DVB-S, DVB-C, DVB-T and DVB-H.
1) Different systems conver different frequency band, different wideband design needs different power comsumption;
2) Different systems have different consumption requirement.
3) Different systems have different system specs, such as...
Hi all,
I have some questions on the frequency accuracy or stability: (Please help me analyze it)
1) What's the frequency accuracy? what's the frequency stability? what are the differences between the accuracy and stability?
2) There is a specification on crystal, frequency stability xxppm...
Hi all,
I am using the N_StateMod in ADS, but I don't know how to use the "file based" of its inner item--StateArray. Please see the following picture. Thanks!
Hi BigBoss,
Could you explain the measurement more because I am a beginner? and whether are we need to test N times and then get the RMS value?
Thanks!
Borber,
what's the emitter folover/folower? could you explain it more for me. Thanks!

Pthoppay,
1) There is oscillation at the collector terminal.
2)
What's you mean? could you explain it more because I am a beginner. Thanks!
3) Do you have its ebook? could you...
Hi all,
Are there some literatures on this topic?
Thanks!

Hi GL XTASA,
Your analysis seems to calculate sensitivity of receiver. could you explain more about the following questions?
1)
How to deduce the relation of sensitivity and oscillator influence...
