What is continuous-time frequency?
Continuous-Time Sinusoidal Signal
ω=2πf is the angular frequency in radians per seconds. f is the frequency of the signal in Hz.
How is the signal called continuous in time?
A signal is considered to be a continuous time signal if it is defined over a continuum of the independent variable. A signal is considered to be discrete time if the independent variable only has discrete values.
What is continuous-time?
A continuous-time signal has values for all points in time in some (possibly infinite) interval. A discrete time signal has values for only discrete points in time.
What is difference between continuous and discrete signal?
A signal, of which a sinusoid is only one example, is a sequence of numbers. A continuous-time signal is an infinite and uncountable set of numbers, as are the possible values each number can have.
