Hi all, I have a question about exp(j2*pi*n) signal . This signal is a impulse in frequency domain. I could not get much intuition about this signal. but I see this signal used in many applications related to radar. what is its property like? What difference will it cause in transmission( in terms of distance travelled, energy , power, reflections) when it is low frequency and high frequency. Thank you so much. I got really good replies for my previous question on this forum.. Thanks a lot to everyone Regards, Mahadevi.

Thanks a lot to everyone Your signal is a sine wave in the time domain -- there is huge amount of info online about sine waves that you can study. But just a comment about intuition of this signal: I like to think of sinusoidal signals as efficient ways to transmit something. RF signals, power lines, audio tones, light (to some extent), tsunamis -- all sine waves, and all efficient ways to "move something" over distance. -Jeff

The exp( ) is an eigen value, that is the output of the channel has a direct relation (in a SISO system its a multiple). > What difference will it cause in transmission( in terms of > distance travelled, energy , power, reflections) when it is low frequency > and high frequency. High frequency is preffered becuse of the less interference (ISI), I dont know if it has something to do with distance traveled !
