Baseband communication is the simplest form of analog communication.
We use analog communication techniques for analog message
signals, like music, speech, and television. Transmission andreception of analog signals using analog results in an
inherently noisy received signal (assuming the channel addsnoise, which it almost certainly does).

We use analog communication
techniques for analog message signals, like music, speech, andtelevision. Transmission and reception of analog signals using
analog results in an inherently noisy received signal(assuming the channel adds noise, which it almost certainly
does).
Here, the transmitted signal equals the message times a
transmitter gain.
An example, which is somewhat out of date, is the wireline
telephone system. You don't use baseband communication inwireless systems simply because low-frequency signals do not
radiate well. The receiver in a baseband system can't do muchmore than filter the received signal to remove out-of-band noise
(interference is small in wireline channels). Assuming thesignal occupies a bandwidth of
Hz (the signal's spectrum extends from zero to
), the receiver applies a lowpass
filter having the same bandwidth, as shown in
[link] .
We use the
signal-to-noise ratio of the
receiver's output
to evaluate any analog-message communication system. Assume that
the channel introduces an attenuation
and white noise of
spectral height
. The filter does not affect the signal component—we
assume its gain is unity—but does filter the noise,removing frequency components above
Hz. In the filter's output, the
received signal power equals
and the noise power
,
which gives a signal-to-noise ratio of
The signal power
will be
proportional to the bandwidth
;
thus, in baseband communication the signal-to-noise ratio variesonly with transmitter gain and channel attenuation and noise
level.
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these
Jharna
continue..
sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision.
play therapy.
speech therapy.
Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game.
string and beads game.
the more you interact with the child the more effective
Jharna
results you'll get..
please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
but trust the process and be strong and patient as a parent.
