The Signal Man - The Signal Man Through out the story Dickens has created a sense of horror and suspension in his description of the setting, landscape, physical surroundings and the weather conditions. At the start of the story the signal man hears a voice shouting down to him from up above, instead of looking up in the direction he heard the voice coming from, he turned himself about and looked down the line. This seems rather odd as you would normally look to where you heard the voice. The man shouting down to him, was on a high cliff and he was steeped in the angry glow of a sunset and the signal man’s figure was foreshortened and shadowed, down in the deep trench so it was rather awkward for the man to see who he was shout to....   [tags: English Literature] 1784 words

One of his many ways of building tension is through his descriptive passages and dark-toned speech of the Signal man - and occasionally the narrator. There is a very powerful opening as the Narrator shouts "Halloa. Below there!", which are key words throughout this chilling short story. The exclamation marks at once produces an alarming suspense and raises tension as the reader cannot acknowledge which character speaks....   [tags: English Literature] 1465 words

When you tune into an AM radio station, for example 1560 on the AM dial the transmitter’s sine wave is transmitted the data at 1560,000 hertz. What this number essentially means is that the sine wave repeats every 1560,000 times per second. The data is modulated onto the carrier wave by changing the amplitude of this sine wave....   [tags: Engineering Radio Design ] 1780 words

How the Heart Works - How the Heart Works The cardiac electrical system The heart generates its own electrical signal, or impulse. This electrical impulse can be recorded by placing electrodes on the skin of the chest, thus producing the electrocardiogram (ECG, or EKG). The heart's electrical impulse arises in the upper portion of the right atrium and spreads across. As it spreads, it triggers the heart muscle to contract in a coordinated fashion. If the electrical signal becomes deranged in some way, the efficient pumping action of the heart may deteriorate, or stop altogether....   [tags: Papers] 418 words

Comparing "The Red Room" and "The Signalman" - ... The Red Room also conveys scenes of a Gothic nature quite well by using techniques which are also employed by Dickens when he wrote The Signal-man.
