serial vs parallel data transfer
You are right...
The parallel ports are faster, and esier because they dont requiere multiplexing. Tthe thing is that since the serial ports reqier less pins, or lines, the HW can be smaller. So engeniers have dedicated more efort on serial ports and protocols...
logic inverter
JUST TAKE TOW C-MOS TRANSISTORS, ONE N-MOS, AND THE OTHER ONE P-MOS. CONNECT THE GATES TO THE INVERSOR INPUT . CONECT THE P- MOS SOURCE TO THE OUTPUT AND DO THE SAME WITH THE N- MOS DRAIN . THE P- MOS DRAIN MUST BE CONNECTED TO POWER, AND THE N-MOS SOURCE MUST BE...
What is a carrier?
when you try to send information througt any comunication cahnl you need anything take this information from one side to other side . A frequency carrier do this thing without a frequency carrier you can´t take a comunication ain a chanel with many disturance lke the air.
some question about ASIC
In ASIC you have 3 diferent developments alternatives:
Custom : where you have a completly control in your design. It is expensive and requires a large development type.
Semicustom : here you must consider somo especificatoon from the producer .
Programable: you must...
