continuous signals

continuous signals
a signal of continuous amplitude or time is known as continuous signal or analog signal....
this signal is having some at every instant of time....

examples of continuous signals:-
1.sine wave
2.cosine waves
3.triangular wave
4.temperature
5.pressure
6.sound

characteristics of continuous signals
1.for every fix value of t,x(t) is a periodic in nature

2.if the frequency (1/t) is increased then the rate of oscillation also changes...
