Signal transduction refers to
Signal transduction refers to any process of changing one signalto signal of another type. An example would be a series of pulsinglights into the sound for the word: “Help”. Discuss how thistransduction could be done by a device.
Answer:
Transducer converts signal from in one form to the other, say ,from light to sound. There are different transducers availabledepending on the types of signals. Here, I would like to discussthe basic functioning of sound recorder on paper.
Consider a diaphram and when sound energy hits the diaphram ,the diaphram vibrates corresponding to the vibrations of the sound.Now, if we attach a needle to the diaphram , the needle vibratesaccordingly thereby the drawing the pattern of sound waves andhence recording the sound. So, here the practical sound signal isconverted into a visual marking from where we can reproduce thesignal. This a typical example of this.
Other such common examples are microphone. Similar to theexample mentioned above, the sound energy is converted to themechanical vibrations which is the function of transducer.
Another example is that of antenna. Antenna while transmittingtake the electrical signals and converts to the electro magneticsignals. The corresponding changes in the electrical signal isreflected in the electromagnetic signal.
