telecommunication

Greetings I am considering getting a cheap tablet for a telecommunication diploma? As it's hard to find a suitable and cheap option for an andorid tablet. Most the work is vocational, however, until getting a job it is recommended to get a temporary tablet that would be suitable for outdoors...

Hello:) I'm working on this old touch-tone telephone (Statesman 9040R - see picture). I'm essentially building a new circuit from scratch - it won't be connected to the phone lines but will instead be an arduino based interactive playback circuit. I would still like to understand how the old...

Hi all, I'm currently reworking an old touch-tone telephone, which involves redesigning the circuit to avoid the whole telephone line high voltage AC circuitry etc. In my first prototype I got on fine using an IK semiconductor 91214b IC to do DTMF generation, with the keypad keys connected as...

I decided I would try my hand at programming an ESP32 using CLion instead of the Arduino IDE, so this project is running in the ESP IDF (toolchain?) and C language. I couldn't find the file for setting the settings, so all pins and settings are default - it would fill out the whole post if I...

Hello! I am currently doing a school project where we are going to design a direction finding system using antennas and an automated robot arm to adjust to angle. From what we have read the most reasonable choice of antenna is either a yagi or parabolic antenna. The robor arm is fairly small...

Hello! I am not sure if this is the right place to ask, but I am stuck already a couple of days. I have implemented a soft Hamming decoder (LLRs) in MATLAB and now I have to create a soft-output for this decoder. My attempts all failed, since the soft-outputs do not match the hard-bits. The...

Hi. At first I want to appologize for my English, it isn't my native language, so sorry for any grammatical errors. So, here is problem that I'm struggling with for a while (2-3 months). My friend goes to shoot various events and actions, he ussualy has 5-6 cameras with 3-4 cameramem, but...

For a university project, I am designing and am further required to build a sensor fusion device for soil quality measurement in agricultural soil. The device will measure the volumetric water content (VWC) in the soil, the temperature of the soil and the light levels that the soil is exposed...

Hello, I'm studying telecommunication electronics at Institut Teccart, a private college (CEGEP) in Montréal-Canada, and I'm trying to figure out which kind of job available on the market I'd enjoy. I'm holding a computer science college diploma but I went into telecom because I wanted...

Hey all, I got stuck on a homework question about narrowband instantaneous power. First of all, the description of the quesion: Assume a mobile traveling at a velocity of 20 km/h receives two multipath components at a carrier frequency of 1000 MHz. The first component is assumed to arrive at...

Hello, I'd like to know if python programming skills could be an asset for a telecommunication technician/engineer. Does anybody have some experience with python into the field ? I'm currently studying telecommunication electronics in a College in Montréal, Canada and i hold a diploma in...

why does 1/4 wavelength have to have a ground plane and 1/2 doesn't? I know that an antenna that has half a wavelength does not need the ground plane (example a dipole antenna) and when using a wavelength of 1/4 it is usually necessary to have the ground plane (planar antennas [PCB]). My...
