∴ Sin(t) is an anti-symmetric signal or an odd signal. Explanation: A signal is called an energy signal
if the energy satisfies 0<E< ∞ and power P=0

Which of the following signal is an energy signal?
∴ Sin(t) is an anti-symmetric signal or an odd signal. Explanation: A signal is called an energy signal
if the energy satisfies 0<E< ∞ and power P=0
.
What are energy signals?
A power signal
has infinite energy
and an energy signal has zero average power. Transient (finite duration) signals are energy signals while periodic signals are power signals.
What is energy signal with example?
In other words, energy signals have values only in the limited time duration. For example,
a signal having only one square pulse
is energy signal. A signal that decays exponentially has finite energy, so, it is also an energy signal.
Is e’t an energy signal?
= e . t t tu E . = T ; hence,
it cannot be an energy signal
. Since P is finite, is a power signal and its energy is infinite.
How are signal classified?
Signals are classified into the following categories:
Continuous Time and Discrete Time Signals
.
Deterministic and Non-deterministic Signals
. … Real and Imaginary Signals.
What is the use of random signal?
Signals can be divided into two main categories – deterministic and random. The term random signal is used primarily to
denote signals
, which have a random in its nature source. As an example we can mention the thermal noise, which is created by the random movement of electrons in an electric conductor.
Why is energy and power a signal?
This signal
has finite energy and zero power i.e.
Hence, it is an energy signal. This signal has infinite energy and finite power i.e. Hence, it is a power signal.
What is signal and system?
Signals and Systems. A signal is
a description of how one parameter varies with another parameter
. For instance, voltage changing over time in an electronic circuit, or brightness varying with distance in an image. A system is any process that produces an output signal in response to an input signal.
What is even signal?
Even signal is a
signal which satisfies the relation f(t) = f(−t)
. Even signal is symmetric about the y-axis. Example: cost. … Odd signal is symmetric about the origin. Example: sinωt.
What are the basic operations on signals?
Addition, subtraction, multiplication, differentiation, and integration
fall under the category of basic signal operations acting on the dependent variable.
What are exponential signals?
A real exponential signal is defined as.
Where both “A” and “σ” are real
. Depending on the value of “σ” the signals will be different. If “σ” is positive the signal x(t) is a growing exponential and if “σ” is negative then the signal x(t) is a decaying exponential. For σ=0, signal x(t) will be constant.
Is e JWT a power signal?
What is the power possessed by a signal exp(jwt)? Explanation: The
power = Energy/Time period for a periodic signal
. Hence, Power = 1. … Explanation: Any two instants, t and t + 2pi will be equal, hence the signal will be periodic with period 2pi.
What is average signal power?
The average power of a signal is
the average of the instantaneous power
– if your signal has a power of 1 half of the time and 3 the other half, then the average power is 2.
