[Discuss-gnuradio] Timer Event with GRC(Relationship among Sample Rate, Frequency, Decimation)

[hafiz zimran]

Hi

I am using signal source and variable sink to generate a variable with name” carrier_frequency”.

I am interested to transmit signal at 920 MHz & 2 GHz.

For that purpose, the signal source parameters are as follows:

Sample Rate: 1000

Waveform: Triangle

Frequency:1

Amplitude:2G

 

The variable source parameters are:

Variable : Carrier frequency

Decimation: 125

 

What is the relation among Sample rate, Frequency and decimation?

PLEASE GUIDE ME IN THIS REGARD
