Visoka frekvencija je nosilac informacije, gdje se nakon demodulacije informacija pojavljivala u obliku dogovorenih znakova Morseovog koda. Kratko trajanje tona je u tom smislu označavalo točku, a vremenski duže trajanje crtu, gdje je su određene kombinacije točaka i crta označavale pojedina slova abecede ili brojeve. Na taj je način, na primjer slijed od tri točke, tri crte i ponovno tri točke (<b>… - - - …</b>) označavao SOS međunarodni poziv u pomoć koji su tradicionalno slali brodovi u slučaju opasnosti. </p> <div class="mw-heading mw-heading3"><h3 id="Radio">Radio</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Elektri%C4%8Dni_signal&veaction=edit&section=5" title="Uredi odlomak: Radio" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Elektri%C4%8Dni_signal&action=edit&section=5" title="Uredi kôd odjeljka Radio"><span>uredi kôd</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="/wiki/Radio" title="Radio">Radio</a> se razvijao usporedno s radiotelegrafijom te je prva eksperimentalna radio postaja otpočela s radom 1897. godine.

Pojavom sve većeg broja radio stanica postojeći frekvencijski prostor postao je jednostavno preuzak za otvaranje novih te je, do tada vrlo slabo prihvaćen, FM radio sa znatno boljom kvalitetom prijenosa signala ipak usvojen početkom pedesetih godina, gdje je britanski BBC započeo emitirati FM program 1955. godine. Premda je emitiranje FM programa usvajano relativno polako, do danas je FM radio u komercijalnoj primjeni praktički potpuno istisnuo klasični AM radio.

Razvojem elektronike i pratećih uređaja postavljani su sve kvalitetniji standardi i za reprodukciju govora i glazbe te danas smatramo da prijenosni frekvencijski spektar elektroakustičkih uređaja za reprodukciju tonskog frekvencijskog područja treba težiti rasponu frekvencija od 20 Hz pa sve do 20 kH, premda valja napomenuti da ljudsko uho ipak ima nešto uže čujno područje. Frekvencijsko područje električnog signala može se prostirati i ispod 20 Hz, kada govorimo o <a href="/wiki/Infrazvuk" title="Infrazvuk">infrazvučnom</a> području ili iznad 20 kHz kada govorimo električnom signalu <a href="/wiki/Ultrazvuk" title="Ultrazvuk">ultrazvučnog</a> područja. Područje električnih signala ultrazvučne frekvencije prekriva se iznad neke granice s područjem električnih signala područja najnižih radio frekvencija (valno područje ekstremno velikih valnih duljina). Povišenjem frekvencije električnog signala ulazimo u brojna frekvencijska područja rada srednjevalnih i kratkovalnih odašiljača i stanica, brojnih programa televizije, te područje frekvencija koji se koriste za vojsku i policiju, mobilne uređaje i satelitske komunikacije, radare, i td. </p> <div class="mw-heading mw-heading2"><h2 id="Analogni_i_digitalni_oblik_električnog_signala"><span id="Analogni_i_digitalni_oblik_elektri.C4.8Dnog_signala"></span>Analogni i digitalni oblik električnog signala</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Elektri%C4%8Dni_signal&veaction=edit&section=10" title="Uredi odlomak: Analogni i digitalni oblik električnog signala" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Elektri%C4%8Dni_signal&action=edit&section=10" title="Uredi kôd odjeljka Analogni i digitalni oblik električnog signala"><span>uredi kôd</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Pod pojmom analognog električnog signala podrazumijevamo, pojednostavljeno rečeno, takav električni signal koji je u svakom trenutku vremena prisutan u sustavu (Slika desno: fig.1).
