In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The IEEE Transactions on Signal Processing includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as any observable change in a quantity over space or time, even if it does not carry information.In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typically provided by a sensor, and often the original form of a signal is converted to another form of energy using a transducer. For example, a microphone converts an acoustic signal to a voltage waveform, and a speaker does the reverse.Another important property of a signal is its entropy or information content. Information theory serves as the formal study of signals and their content. The information of a signal is often accompanied by noise, which primarily refers to unwanted modifications of signals, but is often extended to include unwanted signals conflicting with desired signals (crosstalk). The reduction of noise is covered in part under the heading of signal integrity. The separation of desired signals from background noise is the field of signal recovery, one branch of which is estimation theory, a probabilistic approach to suppressing random disturbances.
Engineering disciplines such as electrical engineering have advanced the design, study, and implementation of systems involving transmission, storage, and manipulation of information. In the latter half of the 20th century, electrical engineering itself separated into several disciplines: electronic engineering and computer engineering developed to specialize in the design and analysis of systems that manipulate physical signals, while design engineering developed to address the functional design of signals in user–machine interfaces.
Hello. Anyone experiencing network problem with TNT/Smart? It's been few weeks already. Hindi siya stable. Parang mas madami pa yung oras ng packet loss niya kaysa sa oras na makakapag browse ka. Taguig area.
Pa help naman diko alam kung akin lang may problema. Medyo mabagal tapos di stable yung signal ng data ko pero sa ibang phone okay naman malakas hatak ano po possible way para ma fix to

I'm really stuck w/ this slow internet connection. I already checked the tower near my place it has 3G/4G capabilities, also i already checked my phone it's 2G/3G. I don't think my phone have a problem coz this is a legit phone. More like genuine .. Can anyone help me?
Permission to post po mga boss..
..ask ko lng po..na e encounter nyu rin po b to??
.as of now po patay sindi ang signal(4g) ni globibo dto samin(cavite area)..or ako lng b nkaka encounter neto?
..
Anu po kaya ang problema..slmat po sa sasagot..

Gs+injector po gamit q
Guys pahinging pro advice paano palakasin signal ng phone ko ..
Halos 1 bar lang kasi minsan nga wala talagang bar .. Pa tuLong naman on how to resolve this probLem of mine .
hello mga kaphc patulong po kasi yung cellphone ko walang signal kahit ano ilagay na sim pero dati okey naman po bakit kaya?? sana may tumulong salamat
Last year yung SINR ng 936 ko is 6dB to 9dB, after 1-2 months nging -1dB to 3dB then ngayon lang nangyare naging -4dB yung lowest. Cavite area po. Anyone?
pasinsya po hindi working yung plus sign sa keyboard ng laptop. kapag inaactivate ko po yung pang freenet ko, pgkaraan ng ilang minuto nagiging H nalang tas hindi na babalik yung plus. may alam po kyo na solusyon dito? patulong po.
Magandang umaga sa ating lahat
Ask ko LNG po sinu po pwede makatulong panu po palakasin signal ng tm dito saamin 1bar LNG po kc signal dito hirap ako magdownload ng ehi
Salamat sa makatulong?:bigtears::peeking:
Mga bossing, may naka experience na po ba tulad nitong sa akin, ang mf65m smartbro pocket wifi ko wala pang one month sa akin, una, okay ang DL at UL nya. DL speed 1.20+ Mb/s up to 2.60 Mb/s at ang UL 0.80Mb/s up to 1.44Mb/s. Below, is a screenshot nang last speedtest ko. Ngayon, biglang humina...

Mga KAPHC.
Maitanong ko lang po kung papano ang gagawin sa mababang SINR at Signal bar para ito ay mapataas. 1bar na lang ang signal nya at negative(-) ang SINR? Salamat mga kaPHC
Mga ka-ph, may signal ba kayo ng 4G ng smart? Sa Dasmariñas, Cavite area ako. Bumili na kasi ako ng bagong pink sim e. Pero no signal padin yung 4G ko sa 936 tsaka sa phone. Nung una akala ko blocked lang dati kong kickstart pero ito bagong sim na e wala padin. Maintenance ba? Salamat po sa sasagot.
mga boss tanong ko lang kasi wala ng masagap na signal sa kahit anung frequencies yung toy ko dito sa area ko, ibig sbhn ba nito wala ng wimax dto sa amin??
