**"Sine Wave" block in Simulink vs "Sine Wave" block in Signal Processing Blockset**Kindly refer to figure below.
What is the different between the sinewave generated by "Sine Wave" block in Simulink vs "Sine Wave" block in Signal Processing Blockset (SPB)?
I wish to understand the "physical" meaning and difference. I will appreciate if someone can give a "real-world" example in which sinewave generated by SPB is useful.
Thanks

**Converted Sine wave from DC-AC inverter not having the same amplitude as the Square Wave**I have a Inverter with a DC input and output as a Square wave. My aim was to convert this DC input into an AC Sine wave. Therefore, I had placed LC filter at the output of the inverter.
I did get a square wave which has the same amplitude as that of the input DC voltage. But when I convert this into a sine wave, the amplitude is decreased irrespective the values I change. The following are the parameters I have used:
DC input : 170 V
Inverter: 2-arm four diode Universal Bridge (Ideal Switches)

**superposition of a square wave over a sine wave**Hi all,
I am new to VHDL programming. My task is to generate a high frequency
square wave(500 Hz) super positioned over a low frequency sine wave(5
Hz). how can this be achieved in VHDL. I know how to generate both
these waves separately, but i dunno how to generate them together and
superposition them. i would be thankful if someone could help me in
this task. even your valuable ideas will be quite useful for me.

You can create a sampled sine wave using the sin function (the result

**Square wave vs sine wave oscillator for mixer**Hi All,
I have a 80MHz crystal clock oscillator that I am using to clock ADCs
and DACs and an FPGA in a design that I am working on. I also would
like to use the same 80MHz clock as the Local Oscillator (LO) reference
for a mixer to mix my ADC outputs up from 8-28MHZ to 88-108MHz.
Do you know if I can run a square wave into a mixer? or will this cause
my issues?
Also the mixer requires a LO power of about +10dBm (50ohm). Is there
any easy way to get the clock oscillator up to this kinda power level
to drive the mixer.
Regards,
Paul Solomon

I'm using simulink. My incomming data is sine wave and i need to

Well, for test, i did some thing like, using signal generator i

so, please let me know what to do.

What is the method you used for converting sine into square. How does
fft of sine will lead to square? Infact, if you combine odd harmonics
of sine (10 harmonics will do), you may get square.

**In phase and quadrature components of a sine wave and a cosine wave**Hi,
I have a question that seems simple but is surrounding my mind. From my
understanding, a signal can be represented by its in-phase and quadrature
componentes (which are low pass signals). The relationship is the
following
A(t)*cos(wt +phi(t) ) = si(t) * cos(wt) - sq(t) * sin(wt) , being si(t)
and sq(t) the associated I and Q signals respectively.
So, imagine I have just cos(wt), does it means that si(t) is always = 1?
I.e, samples IQ IQ IQ IQ IQ IQ would be
And what about sin(wt), would be sq(t) = -1 amd si(t) = 1, i.e. samples IQ
IQ IQ IQ IQ IQ would be 0-1 0-1 0-1....

**simulink: discrete sine wave to array?**Hello
I've got a sine wave block generating 16 discrete values for a one
period sine signal. How can I put all 16 values into one array?
Thank you
Sincerely
Lore
Hi Lore,
to have the array in the matlab workspace, use a 'to workspace' block
and take the array from the result variable (apply proper simulaion
settings for the model in addition -> fixed step, discrete).
To have an array in simulink, use cascading 'unit delay' blocks and a
'mux' collecting their outputs.
Cheers,
Robert
