a pulse (dirac's delta).
The unit step function is also known as the Dirac delta function. It can be thought of as a function of the real line (x-axis) which is zero everywhere except at the origin (x=0) where the function is infinite in such a way that it's total integral is 1 - hence the use of the word 'unit'. The function is not a strict function by definition in that any function with the properties as stated (0 everywhere except the origin which by definition has a limit tending to 0), must therefore also have an integral of 0. The answer is therefore zero everywhere except at the origin where it is infinite.
A Liter
kilo
kPa is a unit of pressure, kg is a unit of mass
Below code generates unit step function n1=-4; n2=5; n0=0; [y,n]=stepseq(n0,n1,n2); stem(n,y); xlabel('n') ylabel('amplitude'); title('unit step'); It results in a unit step whose value is 1 for time T>0.
YES, unit step function is periodic because its power is finite that is 1/2.. and having infinite energy.

standard of valueThe function of money as a measure of value.
One extra unit of money equals 1 extra unit of utility.

u(t)-u(-t)=sgn(t)
Theta can take units of radians or degrees. However, the sine function itself does not have units. It returns a unit-less value.
When the numerical value of a quantity is equal to the unit of that quantity, it means that the quantity being measured is equal to 1 in that unit. This often simplifies calculations and conversions in physics and mathematics.
Both pulse and impulse are the types of unit step function. In case of impulse the response gains the value for short duration of time and then becomes 0 while in case of pulse it is not neccessary that the value of response become 0 after an interval it may remain constant also.............
There are an infinite number of answers to this question. To demonstrate, let us write it as a function (where urepresents the unit of measurement):a * b * 1/2 = 30u2a = 60u2 / bNow you can plug any b value into that function, and get a value for a that meets the conditions of the question. For example, if b = 20cm then a = 60(cm2) / 20cm, which equals three centimeters; If b = 3.2Lbs, then a = 18.75Lbs; if b = 120 parsecs, then a = 0.5 parsecs.
