Answer / girish

nyquist freq or nyquist rate is equal to sampling freq

Answer / muhammad rana usman

which signal is twice of its original signal is called
sampling theorem

Answer / shalini

"a bandlimited signal can be constructed exactly if it is sampled at a rate atleast twice the max. frequecy component in it."

Answer / abhinav kumar

A continuous time signal is firstly converted to discrete
time signal by sampling process and the process by which
reconstuct the continuous time signal(original signal).
A continuous time signal recovered back if the sampling
frequency is Fs >= 2Fm.

Answer / shanu

sampling theorem is the continuous singnal are sampled at
that frequency rate or equal time period

Answer / lavanya

sampling is a process where the continuous time signal is converted into discrete time signal.for the effective reconstruction of the signal at the receiver it should satisfy the nyquist theorem.

i.e "A band limited analog signal can be effectively reconstructed when the sampling fq >= highest frequency of messege signal"

THANK U

Answer / umer farooq

sampling theorem : A continuous signal can be completely represented in its samples and recovered back if it follows the nyquist condition i.e fs≥2fm, where fs is sampling frequency and fm is max freq. in the signal.

Answer / ashu

fs>= 2f

Answer / rajendra prasad

sampling theorem defind as the sampling frequency must be
greter than the dual frequency thi is shown in equentially

Fs>=2f

Answer / dhanasekaran

the required frequency bandwidth is proportional to the
signaling speed, and that the minimum bandwidth is equal to
half the number of code elements per second.

fs>=2f
