[Discuss-gnuradio] Control loop in GNURadio

2014-08-18 Thread Daniele Nicolodi
Hello, I need to implement some control loops as GNURadio blocks, I had a look at the code base and I found the gr::blocks::control_loop class which, despite his name is specialized for phase lock loops. Am I missing something or a general PID control loop implementation does not exist in GNURadio

Hi Tom, As hilbert transform is a high-pass filter which only allows the positive frequency components.And we know that only a complex signal can have a single sided spectrum,not a real signal.So, i am still confused that why the signal isn't showing any imaginary part??May b i am not understanding

[Discuss-gnuradio] Tracking PLL phase error

2014-08-18 Thread Daniele Nicolodi
Hello, I'm using the gr::analog::pll_carriertracking_cc() block to track a very stable signal of which I don't know the exact frequency and of which I want to detect (small!) phase oscillations. In my tests I discovered that the tracked signal has a residual phase modulation that I would not expe

[Discuss-gnuradio] Branch for Testing Parallel Build Issue

2014-08-18 Thread Michael Dickens
< https://github.com/jmcorgan/gnuradio/tree/fix-parallel-build > The goal of this branch is to fix the parallel build issue that's been plaguing GNU Radio's CMake build system pretty much since day 1. The shortest explanation of this fix is that CMake has a bug in it when handling multiple gen

[Discuss-gnuradio] fcdproplus (Funcube Pro Plus) Module?

2014-08-18 Thread Thomas M. Alldread
Greetings Marcus, Thank you for your prompt response and assistance! Once I knew that it was looking for a software module I realized I probably specified the wrong location for the fcdproplus module installation. The instructions on GitHub state to specify the path "". I initially
