Time division multiplexing for analogue signal

AI Thread Summary
The discussion centers on the implementation of Time Division Multiplexing (TDM) for an upconverted 1 GHz signal in an OFDM system. The initial response suggests that while TDM can be applied, it may not be scientifically sound as it creates a new spectrum. The user clarifies that GMSK is a digital modulation technique, and their focus is on analog signals after upconversion. They inquire about the feasibility of using Frequency Division Multiplexing (FDM) for signals at 1 GHz and 1.2 GHz. The conversation highlights the complexities of multiplexing techniques in the context of analog signal processing.

Hi guys, I am designing an OFDM system and then upconverted at 1 GHz. Now I have an idea of implementing TDM for this 1 GHz signal.

Is it possible, please explain from theoretical point of view and if possible, please help from MATLAB perspective.

Thank you very much,

i think that if you mean by TDM gsm system "for example" then its easy.
but not good from science point of view as you have just created new spectrum for gsm or ay TDM system.
any way in MATLAB use acarrier and multiply it with your modulated data by GMSK.
good luck
 
Hi there, thanks for your reply. But GMSK is for digital modulation. After upconverting my signal to 1 GHz, it will be analogue then.

For an instance, say I have a signal with carrier frequency of 1 GHz and 1.2 GHz, can I use FDM to multiplex them?

Thank you!
 

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
