Hello

I have to create a sine wave from simulink with a max value of 3 and a
minimum value of -1. i tried to do this in simulink,but i kept getting
the sinewave being centered at 0 with 2 volts above it and 2 volts below
it. thus i was getting a max value of 2 volts and a min value of -2
volts.
i know the peak to peak amplitude of my graph should be 4 volts so i set
my amplitude to 0.5*(4),frequency to (2*pi*2) and sample time to 1/1000.
the phase and the bias is 0.

i get a sinewave but not with the max and min values i want.

How can i create a sinewave with a max value of 3 and a min value of -1?


add it to a constant 1 value maybe?


or even better, set the bias to 1. Have a look at the sine wave
documentation for more details on the different parameters:
