serial ports laptop voltage
I have a PIC project that transfers data to PC via RS232. This thing works flawlessly on my desktop PC at 57600, however on my laptop it is giving me problems. Sometimes it works ok for 20 seconds or sometimes 5 seconds then starts getting errors. Has anyone ever...
I'm trying to transmit A/D Conv samples from the PIC micro to the PC. Currently I've got the RS232 connection working. I tested that by running a terminal emulator and having the PIC send some ASCII.
I'm want to do the PC side software in VB because I want to be able to plot the ADC samples...
50hz square to sine wave
The signal will be varying quite a bit from prob 100hz to 10khz. I'll look into the switch-cap LPF.. thanks..
The AD633 analog multiplier IC can be used to multiply, divide, square signals.. plus it can be used as a voltage controlled amp/filter. It's does a lot...
566 vco sinewave
What i'm trying to do actually is convert the square wave of a PLL to sine. However the PLL will be tracking a changing frequency, so therefore the output of the PLL will be a square wave with varying frequency.
So what is a switched-capacitor LPF? where can I get info on...
converting a square wave to a sine wave
What is the best way to convert a square wave to a sine wave? I was thinking of putting it through a LPF. Basicly, I need to convert the square wave output of a PLL to a sine. Mind you, the square wave frequency is not fixed, it will be changing.
Any...
