How is it possible to represent a complex exponential signal with a frequency of 20Hz using a sampling frequency of 30Hz?

A 20Hz signal must be sampled at a minimum of 40Hz to have a chance of sampling both peaks and to get a reasonable representation it must be sampled at a minimum of 100Hz.For a sampling rate of 30Hz the Nyquist frequency is 15Hz and since 20Hz is above that it will generate the alias signal of 10Hz in the sampled data instead of the original signal of 20Hz. Therefore it is not possible to do what you ask.


How do you calculate Minimum reinforcement?

What is the theoretical minimum system bandwidth needed for a 10 Mbps signal using 16-level Pam without ISI?

To determine the theoretical minimum system bandwidth needed for a 10 Mbps signal using 16-level Pulse Amplitude Modulation (PAM), we first calculate the symbol rate. Since 16-level PAM represents 4 bits per symbol (as (2^4 = 16)), the symbol rate is (10 \text{ Mbps} / 4 \text{ bits/symbol} = 2.5 \text{ Msymbols/s}). According to the Nyquist formula, the minimum bandwidth required is half the symbol rate, which leads to a theoretical minimum bandwidth of (2.5 \text{ MHz} / 2 = 1.25 \text{ MHz}) to avoid inter-symbol interference (ISI).


An analog signal with a bandwidth of 1.5khz is to be digitalised what time intervals should the analog signal be sampled?

as a general rule of thumb, about 5 times the highest frequency for quality reproduction, although one can sometimes get away with a minimum of 2 times. 7.5KHz

A sinusoidal signal.


What is minimum detectable signal in a radar system?

The minimum detectable signal in a radar system is the weakest signal that the system can detect reliably against background noise. It is determined by the receiver's sensitivity and the signal-to-noise ratio of the system. A lower minimum detectable signal indicates that the radar system can detect weaker signals.

Meaning of Discernable?

The correct spelling is discernible instead of discernable. Discernible means to be perceptible or noticeable. It means being visible or recognizable.


How does tracking devices work?

by broadcasting a radio signal. The signal is picked up by a minimum of 3 satellites, which by triangulation can determine where the signal is coming from.

What is the minimum broadband speed required for a WiFi modem to run or transmit a WiFi signal?

Wifi needs a minimum speed of at least 256 kbps. If you're kbps rate is higher than that you should be able to transmit a signal.
