A beginner question

Hi,

I am new to this field and have read one or two books on DSP.
e.g. the famous The Scientist and Engineer’s Guide to Digital Signal
Processing, and so on…

However, I am still get fluctuated on the basic concept.

Could anyone suggest some books as very layman? Thanks.

I’d like to ask very basic question here. Would anyone kindly to reply.

  1. The Complex and Real form are only the formats the represent the
    sine, and they can be interchangeable, is this concept right?

In the GRC,
the USRP source/sink block, there are two choices as output type,
Complex and Short.
and the Audio sink, the only input must be float.

Why the audio sink/source uses only the “Float” as the data flow,
and the USRP use complex?

Thanks!

Practical Signal Processing by Mark Owen is an outstanding book for
those new to the field. He introduces the use of complex numbers in the
first few pages instead of trying to avoid the concept as long as
possible like many such books do.

“Understanding Digital Signal Processing” by Richard G. Lyons also has a
good introductory chapter on complex baseband processing.

Thanks,

Do they explain on the use of filters, mixer of the sine waves too?
