I am working on a senior design project to develop a laser key system.
Currently we are directly modulating our laser with the output of a PIC microcontroller (which is a code fragment that is hardcoded). We are outputting this in the NRZ(L) standard for binary codes, but we want to modulate...
pcm modulation c code
I am part of a senior design project and we are building a system that unlocks a door using a laser as our transmitter.
We have the transmitter built and working, but we don't know where to start on writing the C code for the receiver.
At the moment we are directly...
matching network resistor
Thanks for the responses!
I worked out some of the numbers on the purely resistive attenuator and you are right in order to achieve a match between 600 and 50 ohms you need have at least a loss of 16 dB.
resistive matching network
For a class I was asked to design the insides of a 'black box' matching network.
It is a very simple problem, but I am having some trouble with it.
I have a 600 Ohm generator load, and a 50 Ohm terminating load.
When looking into the box on either side the...
