What is the signum signal are power or energy signal?
The signum signal, defined as ( x(t) = \text{sgn}(t) ), is an example of a power signal rather than an energy signal. This is because it does not have finite energy; its integral over all time diverges. However, its average power can be calculated and is finite, which classifies it as a power signal. In summary, the signum signal is a power signal due to its infinite energy and finite average power.
When you do modulation in time domain you get modulated waveform of modulating signal information and carrier. How can you recognize the upper and lower side bands in time domain modulated waveform?
You need modulation signal(carrier) which is a required signal in order to make envelope of time domained signal(target signal). The modulating signal is imposed on modulation signal.This creates envelope of waveform which is modulated(desired) signal. Now, the desired signals uper and lower sideband of signal strictly depends on modulation signal's bandwidth. Max. peak of that signal is uper sideband and min. peak is lower sideband for this modulated signal.
What is Vulnerable time in terms of CSMACD?
CSMA\CD means that when a Clint want to send a signal if is it free it will send the signal and it happens in other Clint at the same time so the signal will crash and then they will try again later after period of time.
How does the Sampling rate affect frequency?
In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal).
What is the ratio of desired signal to undesired signal in the average power level of a transmission?
The ratio of desired signal to undesired signal in the average power level of a transmission is commonly referred to as the Signal-to-Noise Ratio (SNR). It is expressed in decibels (dB) and quantifies how much stronger the desired signal is compared to the background noise or interference. A higher SNR indicates a clearer and more reliable transmission, whereas a lower SNR suggests that the undesired signals may significantly affect the quality of the communication.

Can a signal be time-limited and band-limited at the same time?
No, a signal that is band limited is not time-limited while a signal that is time-limited isnot band limited.
What is average signal power?
Transmitting any signal requires energy. "Power" is energy per time unit; for example, if 10 mJ are used for the transmission every second, then the power is 10 mW. "Average"... Well, presumably the amount of signal power can change over time, so the average is taken for a certain time period. For example, when transmitting 1's and 0's, it may be that transmitting a "1" requires more energy than transmitting a "0" (depending on how the information is encoded); the average in this case would be taken with the assumption that the same number of 1's and 0's are transmitted in the long run.
What is the time limited signal?
A time limited signal is one that is nonzero only for a finite length time interval.
How find time period of discreet signal?
To find the time period of a discrete signal, you need to identify the time interval between consecutive occurrences of a specific pattern or value in the signal. This may involve observing the repeating pattern in the signal and measuring the time it takes for the pattern to repeat. Once you have identified this time interval, it represents the time period of the discrete signal.
What is periodic signal?
A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.
How high is the average traffic signal?
16.5 feet
What is hourly time signal?
hourly time signal is causes your watch to beep every hour on the hour.
What kind of television signal is Time Warner cable?
A cable signal.
Difference between strobe and handshake signal?
A strobe signal is sent by the signal sender without any regard to the signal receiver. This assumes that the design provides sufficient setup and hold time, along with transmission time, to ensure reliable receipt of the signal. A handshake signal is a bi-directional protocol between the signal sender and the signal receiver, which the receiver uses to tell the sender that the signal has been received. In this system, it often does not matter what the transmission time is, but bandwidth can be reduced since the sender must wait for the handshake to come back from the receiver, effectively doubling the time it takes to send a signal.
Linear discrete time signal?
The linear discrete time interval is used in the interpretation of continuous time and discrete valued: Quantized signal.
Which encoding type always has a nonzero average amplitude?
Pulse-position modulation (PPM) encoding type always has a nonzero average amplitude. In PPM, the signal's average amplitude is determined by the positioning of the pulses within the signal. This ensures that there is always a nonzero amplitude level in the signal, even during silent periods.
