I have a message signal in 400Hz and a carrier frequency in 2000Hz...
what is the frequency for the modulated signal after i modulate the signal...
Can anyone help me or know about the formula how to calculate the frequency for modulated signal....
Sorry, but without more information and some context, it is not possible to answer your question.
What form is the modulation? Amplitude Modulation, Frequency Modulation or ??
Modulating a 2000hz signal with 400hz does not sound quite right for a practical system, or is this an Frequency Shift Keyed (FSK) system where the two frequencies are 400 and 2000hz?
