Thank you to all. I do not have an option of oversampling so I switched from feedback to feedforward solution instead and it seems ok.I have only one issue left....

AGC on FPGA

New thread started 7 years ago
Hi All,I need to create an AGC algorithm on FPGA. I am using some basic algorithm, but I receive input signal in every clock cycle.In AGC algorithm, in case I have...

Thank you very much for your answer. Your 'tone' is absolutely horrible and you should also assume sometimes that you did not understand what others mean by their...

Power Measurement of Complex Signal

Now I tried to multiply H{x(t)} with some gain, say 1.5 in the Hilbert function that works and got similar result - that it does not completely remove negative component.I...

Hi all!I have another question related to this topic. I understood why I need this type of demodulation and now I am trying to simulate the work of Hilbert Filter.Namely,...

Re: SSB Demodulation

In my system I have channelization which takes care of downconversion (quadrature) and filtering. So assumption is that I get baseband signal consisting of only...

Thank you all for replies.However, I do not fully understand the latest. Does the "downconvert with single channel" mean that I multiply signal with real sine instead...

SSB Demodulation

New thread started 8 years ago
Hi all,I am trying to do the USB SSB Demodulation in FPGA.From what I understood, SSB demodulation is obtained by having m(t) - baseband message signal of frequency...

Interleaved ADC Spurs and Levels
