Answer / nataraj k s
Laplace transform of unit impulse signal is 1. i.e., for
all frequencies the magnitude is unity...i.e., impulse
signal is not a periodic signal and hence it has infinite
frequencies...

Answer / sachin
dear f is directly prop to 1/T.so depend on time period.

Answer / nataraj k s
Yes FT of impulse is DC signal i.e., in frequency domain
amplitude is constant for all frequencies(sketch the DC
signal with independent variable as frequency)....so it has
infinite frequencies....FT of impulse is DC signal but
impulse is not DC signal as it will not exist for all
time...
If impulse is a DC signal then we can say that its
frequecy is zero...but clearly impulse is not a DC signal
(time domain)...

Answer / arminder singh
An Impulse signal is a signal which is centered about t=0 hence if we take the Laplace, Fourier or Z-Transform of Impulse system it will come 1, which means if we transmit the impulse signal then it will take entire the bandwidth or in other words its bandwidth is infinite.
Hence conclusion may also be that, we can not transmit an Impulse signal.

Answer / raff
impulse is a signal with zero pulse width or infinite frequency
| Is This Answer Correct ? | 4 Yes | 2 No |
Answer / pristal.mmangattu
the frequency of an impulse signal is infinity,because its
time period is 0 and the freq=1/t,in fact you cannot say
that an impulse appears for a specified time, because if we
do so that means the function changes to a step signal with
unit area under the curve.

Answer / vijeesh
impulse signal is the signal having value only at time
t=0,ie it does not exist practically. it is a mathematical
assumption for describing system characteristics.so that it
does not have any frequency.
| Is This Answer Correct ? | 4 Yes | 4 No |
Answer / efw
impulse signal is defined as
when delta t tends to zero amplitude tends to infinity so when t tends to infinity the frequency becomes zero
| Is This Answer Correct ? | 0 Yes | 3 No |
Answer / sandy
impulse signal is signal which is present only at time 0 and it is zero at other time so its frequency will b 0...
| Is This Answer Correct ? | 2 Yes | 7 No |
Answer / pankaj iete
when we will convert the impulse signal from time domain to
frequency domain
FT of Impulse is DC signal
so frequency is ZERO
