demod | Command line utility based on liquid-dsp for realtime SDR | Audio Utils library

I'm brand new to DSP and I'm experimenting with GFSK modulation to eventually output the signal using ultrasound. Could someone please explain why this set up doesn't work.

I'm receiving a serialized protocol buffer on the ZMQ Pull source and I'm expecting that if I just modulate then demodulate the signal I will get the same protobuf sent, back in the process that sent it (ZMQ push source sending it back). But that ends up not being the case and the byte pattern received after demodulating is off. Could someone explain why my set up doesn't work, Thank you again.

I am fetching images and want to save images into single pdf file.

Below is the code which is creating multiple pdf for multiple images but I want all images should saved into single pdf :

I am trying to interface with an MSI SDR dongle, using an android app

This device is a clone of the SDRPlay SDR device, and is compatible with it's software and drivers

I am trying to interface with this using an OTG cable and android phone

The android drivers for this can be downloaded from here https://www.sdrplay.com/downloads/

It is in the Android tab under the API/HW – V2.11 (15TH NOV 2017) link (https://www.sdrplay.com/anddl.php)

A possible sample code for this driver can be found here: https://www.sdrplay.com/docs/AndroidIntegrationNote.pdf

Before making the full android program it says the library (libmir_sdr_api.a) should be built into an .so library file using ndk-build

I currently have Android's hello-jni sample project from here: https://github.com/android/ndk-samples/tree/android-mk/hello-jni

I have replaced the jni folder using the Android.mk file, libmir_sdr_api.a, mir_sdr.h, initialization-jni.cpp, demod-jni.cpp and demod-jni.h files mentioned in section 3 of the AndroidIntegrationNote.pdf file I linked above

When I execute ndk-build from the hello-jni project folder, I get he following error:

I have found the following code to do an experiment of AM mod and demod. However I cannot run it in on octave as I am stuck on filtered demod as Octave says the format is different... How do I plot these into freq domain?

The code as follows

I have a simple web service that is trying to open a connection to the database.

I am using jax-ws, Oracle 12c DB, Tomcat 9, Java 8.

Can anyone post the correct way to do this?

So far I've downloaded ojdbc7.jar and ucp.jar into the $TOMCAT_HOME/lib directory.

1. What goes in applicationPath/META-INF/web.xml ?

Right now I have the following:

Good day, so i know you can create a select statement and views easily, and do a

I am confused how to use setData, setItemData and setItem method of QStandardItemModel, these method seem have the same effect, i wonder to know which method should i choose to use will be best?

I made a post query to server and got json. It contains wrong symbol: instead "Correct" I got "\u0421orrect". How can I encode this text?

A parse_json function performs it like "РЎorrect";

I found out that

I have a data structure (Circular Doubly Linked List) of N integers. I have to modify it by minimising some quantity. In some cases of arrangements of numbers, I will have to check whether the quantity is minimised by checking the modified data structure in two or more cases. I would like to know if , my attempt is good enough and if any better algorithm is available for those cases. I am not explicitly stating the problem as I would like to solve it myself but for the sake of debugging, we have to take two adjacent elements of the list which have minimum sum and replace them with the sum. We have to calculate the sum of the sums in each stage. (N to 1)

I have created two functions 2 functions, : mod() and demod(), to modify and demodify the list. In those cases, I will mod() the structure for case 1 and store quantity1, demod() it, then mod() it for case 2, and store quantity2. Then, I will select the mod() for that case which has least quantity. index and temp are two pointers where I have to evaluate the quantities. The edited code is given below.
