How to play a Signal at higher sampling rate without changing the frequency content of the signal?
I have a real-time data consisting of (multiplexed) frequencies 79MHz, 34MHz and 127MHz. The data is collected using an ADC of sampling rate 500MSPS. The signal has been captured for 2$\mu$s, hence ...

Why is a multiplexed FM signal broadcasting silence so... spiky?
I'm trying to understand how American FM multiplexing works. As I understand it, your average FM signal can be made out of:
The mono "sum" channel from 30 Hz to 15 kHz, made out of left + ...

Resources on multiplexer and demultiplexer?
If I search multiplexer in Google and start reading, I find sources that describe a multiplexer as a device that selects between several analog or digital signals, then outputs a single signal. For ...

Combining CDMA with differential Manchester-like encoding?
I wonder to which extend it is possible to combine a self-clocking code (like Differential Manchester encoding) with synchronous CDMA, and how it would be done?
Suppose I want to receive some bits ...

The use of FDM for a single message signal
Suppose I have a single message signal, m(t), that is subjected to AWGN upon transmission.
Is there any way that FDM (or any multiplexing strategy) can be used to ultimately improve the SNR of the ...

How is multiplexing on FM signals performed? [closed]
How does multiplexing differ from FM signals to AM signals. If both FM and AM shift the message signal in frequency, then is there a difference between multiplexing for FM or AM signal?

Noise floor of a FM duplex
If these 2 signals, that form this duplex, have ranges of 15-30 [kHz] and 30-45 [kHz] using:
$NoiseFloor_{dBm} =10\log _{10}(k\times T_{0}\times 1000)+NF+10\log _{10}(BW)$ (formula from wikipedia)
