The objective of this assignment is to create a model using Simulink. Submit one

model file for each question.

Q$1)$ Consider sine$$ and cosine$$signals with amplitude and frequency of unity.

Create a Simulink$$based model to do the following tasks:

$1)$ creates the signals;

$2)$ finds the summation of the signals;

$3)$ display graphically the two signals and their summation;

$4)$ repeat step $3$ if the phases of sine$$ and cosine$$signals increase by a $/3$ and $/4,$

respectively.

$5)$ repeat step $3$ if the frequency of the sine$$signal increase by a factor of $2,$ while

phases remain as that in step $3.$

$6)$ repeat step $3$ if the frequencies of the sine$$ and cosine$$signals increase by a

factor of $2$ and $3,$ respectively. The phases remain similar to that in step $3.$

Q$2)$ Consider four sine$,$ cosine$,$ ramp$,$ and step$$signals$.$ The sine$$ and cosine$$

signals have amplitude and frequency of unity. Create a Simulink$$based model to

do the following tasks:

$1)$ creates the signals;

$2)$ finds the summation of the signals;

$3)$ display graphically the four signals and their summation;

$4)$ repeats step $3$ if the frequency of the sine$$signal increase by a factor of $2$;

$5)$ repeats step $3$ if the frequencies of the sine$$ and cosine$$signals increase by a

factor of $2$ and $3,$ respectively.

Note: There is sin signal block but there is no cos signal block. You can obtain cos

signal from the sin signal block by either adding pi$/2$ in the phase or by

differentiating the sine signal block

I need help with this in MATLab. I tried running my code, but it keeps giving errors
