1- Aliasing can affect DFTs, where higher frequency signals can appear as lower frequency signals due to the use of an N point DFT that has a limit to the highest frequency it can detect. Give one approach when using a DFT to reduce the potential of aliasing.

2-. When using the standard MATLAB commands, or the design equations, to design an FIR filter why is it a good idea to check if the design meets requirements ? Be specific.

3-When using the bilinear transform what is meant by “pre-warping” and why is it necessary ?

4- When using one of the classic filter approximations, which approximation should be used if :

the minimum amount of output distortion is desired.

b. the minimum filter order is desired.

5- Give one advantage of using an FIR filter and one disadvantage of using an FIR filter, when compared to an IIR filter design for the same specification.

Advantage:

Disadvantage:

1. Explain how image frequency signals are received in a superheterodyne receiver? how can these signals be rejected? ( Please explain in detail) 2. Why do some superheterodyne receivers use an RF stage while others do not? (please explain in detail)

Please provide examples or situations where you can use higher or lower alpha level

During the process of digital sampling, data can be lost due to aliasing. Analyse this problem and provide at least two possible solutions. Also, determine the rate at which a signal should be sampled, if the highest frequency is 60MHz.

Explain how the following scenarios would affect the experimental Ksp value (lower, higher or no change from acceptable value): ( the chemical used in this titration are Calcium Hydroxide, and the indicator used in this experiment are methyl orange indicator solution) a) The accidental transfer of some solid Ca(OH)2 into the titrating flask. b) The endpoint of the titration is surpassed. c) The Ca(OH)2 solution was not saturated. d) Tap water instead of distilled water was used to make all...

How will the following situations affect your final calculation of molarity of HC2H3O2? (higher, lower, unaffected. be specific) A) You wash the sides of the flask with deionized water to remove any vinegar of NaOH solution adhering to the side of the flask. B) You add 20 mL of water to the vinegar in the flask (assume no drops of vinegar adhere to the side of the flask). C) The tip of the buret is not filled when you start...

Two microwave signals of nearly equal wavelengths can generate a beat frequency if both are directed...

Two microwave signals of nearly equal wavelengths can generate a beat frequency if both are directed onto the same microwave detector. In an experiment, the beat frequency is 170MHz . One microwave generator is set to emit microwaves with a wavelength of 1.410cm. If the second generator emits the longer wavelength, what is that wavelength?

Do higher or lower frequency travel through object easier (ie walls, mountains, etc)? For example 2.4g is able to travel further than 5g with obstacles but X-rays appear to have a better penetration than 5g (ie 5g has trouble penetrating paper but X-ray can do it with ease). I've also noticed in personal experience that shorter antennas also work better in hills (which from my understanding smaller antennas use higher frequencies).
