signal modulation

[yahyaab]

Guys please can any one help me in this question,

What are the parameters of a \carrier" signal, which we can modify to
deliver information from one device to another? What are the corresponding modulation
schemes called?
(b) Can you draw a sinusoidal carrier, modulated by using these modulation schemes, to
deliver the binary stream 00110?

What is given in the lessons?

Have a look at the links of the following page for some modulation techniques:

Hello,

Yes, you are close.
In the example, the ASK has no output when a 0 is transmitted.
An other name could be OOK (on-off-keying).
