Hello,
Ok, I am going to explain the problem again.
I have a message frequency fm and a carrier frequency fc. During 2-stage SSB modulation the fm signal is modulated first time by some intermediate carrier frequency (lets call it fi) that is lower than the actual required fc. The product is...
Hi and thanks for the reply.
I understand the theory behind SSB and getting rid of sidebands and all that as well as the frequency discrimination method.
My question is more specific. Its a 2-stage SSB modulation. In there the message signal is modulated twice. And I was hoping that someone...
2-stage SSB AM modulator
Hello,
I have to make a Scicoslab simulation of a 2-stage SSB AM modulator.
My fm=100Hz and my fc=100KHz from there I can calculate the BPF transfer function but I don't how to implement the second stage. What should by my fc? It cant be the same as during stage one...
Thanks for the reply.
My LAN set-up is as follows: my PC -> wireles router -> modem -> cloud.
Would it be possible to detect where exactly connection drops?? Is it between my pc and router or between router or modem or modem and cloud??
Regards
Hello,
Recently I'm having some problems with my internet connection. So I thought that I could maybe I could write some program to monitor the connection and create a report of some sort about connection quality. Could somebody point me into some resources where i could start?? I know Java and...
No, the idea of that program is that you can connect your module to PC and configure it using this software. Set baud rate, addresses etc. and the connect the module to microcontroller to USART. It saves you the proglem of configuring it with AT commands.
Here is an example.

Hello,
Thanks very much for all replies.
I got this system to work.
What i did was:I connected Tx of pic to Rx of M16C trough a 1K resistor and Tx of M16C to transistor to raise voltage on pic Rx pin. Pins on M16C seem to be very tolerant to different voltage levels as long as there is some...
Hello,
If you just want to configure your module you can use X-CTU. You can download it from this address. I used this software for my project, very easy to use.

Hello,
I'm uncertain about one thing and hope somebody here can clear it out for me.
I need to connect two uC together, one is PIC18F working on 5V and the other one is M16C working on 3.3V. My question is it ok to simply connect them together or do i have to use some level shifting or simple...
Hi
Thank for the reply.
@ rabin2801
Thanks but this is fine I have this part working
I am using java.comms package to communicate with microcontroller.
Yes my problem is with protocol.
I can read a single byte and send a byte but i have problems with reading loads of byte being sent at once...
