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 the time limited signal?
A time limited signal is one that is nonzero only for a finite length time interval.
Why a signal that is band limited is not time-limited while a signal that is time-limited is not band limited Improve Answer Discuss the question Can a signal be time-limited and band-limited at th?
A band-limited signal is one in which the Fourier transform is zero above a certain frequency. In other words it's a signal that ahas a finite frequency content. The simplest case is a pure sinusoidal signal, whose Fourier transform consists of a delta function centred on the frequency of the signal. A band-limited signal can be reconstructed exactly if it is sampled at at more than twice the maximum frequency present in the signal. A time-limited signal is a signal that is zero above a finite. An example of this would be a short pulse. The reason a signal cannot be both band-limited or time-limited is due to their relationship via the Fourier transform. One can show it is impossible for the Fourier transform of a signal with compact support ie either time or band-limited, to also have compact support. A time-limited signal must have a continuous frequency spectrum existing over all possible frequencies and a band-limited signal can only arise from signal existing for all time. Note this indicates in reality it is impossible to have a truly band-limited signal as it would take infinite time to transmit, but it is nonetheless a useful concept and we can produce nearly band-limited signal to a high degree of accuracy.

Distance a driver must signal a change of lane?
Because road conditions and situations vary there is no set distance for a signal. It should given in ample time to warn other road users of your intentions. Signalling does NOT give you the right of way.
How can I effectively use a bicycle turn signal to indicate my intentions while riding on the road?
To effectively use a bicycle turn signal while riding on the road, extend your left arm straight out to the left to indicate a left turn, or extend your left arm out and bend it upwards at the elbow to indicate a right turn. Make sure to signal in advance of making the turn to give other road users time to react.

What is band limited signal?
A signal is said to be a band limited signal if all of it's frequency components are zero above a certain finite frequency. i.e it's power spectral density should be zero above the finite frequency.

How can I effectively use a bike turn signal to improve my safety while riding on the road?
To effectively use a bike turn signal for safety while riding on the road, signal your intention to turn by extending your arm out in the direction you plan to turn. This alerts drivers and other cyclists of your intended movement, reducing the risk of collisions. Remember to check for traffic before signaling and make sure to signal in advance of your turn to give others time to react.
What is the purpose of a bike signal and how does it enhance safety for cyclists on the road?
A bike signal is used to indicate when cyclists can safely cross an intersection. It enhances safety by giving cyclists a designated time to cross, reducing the risk of collisions with vehicles.
