Find the approximate probability of error for an ASK signal with equi-probable binary symbols, if the average signal SNR is 10 d

B, the signal detection uses an envelope detection technique at passband for two threshold detection cases, with a threshold detector having a thresholds of ~1.2 volts (case 1),~2.2 volts (case 2). The standard deviation of the corrupting Gaussian noise is 1. Use Marcum's Q function to create your solution and label a binary transition probability channel model to illustrate your solution results. Draw a bifurcated pdf representation showing the 2.2 volt threshold and the integrated probability areas for your calculations.

Answer:

Using equation

Px|y(i|v) = py|x(v|i) · px(i)

py(v)

Pc = 1 − Pe = 1 − P{mˆ 6= m} = P{mˆ = m}

the above will become

Pe,ML =

M

X−1

i=0

px(i) · Pe,ML/i

= Pe,ML/i

Pr will be 0.8945

Imagine that you had no problems in your life. how would life be different? Write a paragraph.​
valentina_108 [34]
Just think of it. Imagine today you have absolutely nothing going on. You have an entire day ahead of you but there is nothing you need to worry about. Your body is on a routine. Your mind is on a routine. It would be pretty monotonous.

We often do not realize how fast time is passing by because we are busy dealing with things. But imagine if we didn’t have to? Life would go slow.

Since there are problems, we instill gratitude in our minds. But if we had everything and absolutely no problems, gratefulness would never be something we’d consider. We usually realize the importance of things when we don’t have it with us.

Apart from that, our development would be lagging. I say this because so many amazing inventions have been made because inventors spotted a problem and thought they could fix. Similarly, as humans, we may not be motivated to do stuff ourselves.

Motivation is different for everyone, but let’s say you didn’t have to think of becoming independent, many would lose their motivation to find a decent paying job. Challenges in our life builds us up as a person and I feel like even our personal development would fall behind.

I do think that may be people wouldn’t stress if life had no problems.

In life, we are the problem solvers. Everything is a problem if you think of it that way but at the same time, nothing is a problem if you take it that way. But human nature is such that we find ways to create problems even if it does not exist. What a problematic life looks like to us could be someone else’s peaceful life.

Life without problems wouldn’t be like life at all and it definitely wouldn’t a roller coaster ride with a story that’s worth telling.
