Analog VS Digital 03/25/18
Image:
Summary: Waves are known to carry energy, but they can carry messages, as well. Signals are made by a transmitter. From there, the signals are sent to a receiver. The receiver then converts these signals into a message. Signals can be either digital or analog and the difference is that digital signals are like small pulses (like made with the slinky) whereas analog signals are ongoing waves (like from the activity). An example of analog vs digital in this instance could be represented by a clock. An analog clocks ticks which is an ongoing movement, while a digital clock changes time every so often. Fun Fact: More complex messages can be sent through a digital format by sending more pulses, but in order for this to happen, it takes time. This is why when you are streaming in a higher resolution or downloading an image in a high resolution it takes more time than something of lower resolution.
S&EP- Using Models: A model is an example, most typically a smaller version, to represent a system so you can understand how it works. My group and I used slinkies to model the difference between transmitting digital and analog signals. To model digital signals, we had one person create a message of 10 zeros and ones in any order. That person then bumped the receiver hand accordingly; one bump for one and two bumps for 0. The receiver would call out the numbers as he/she received them so the image generator could copy them down. After this, we replicated an analog signal in which the transmitter created waves of different amplitudes along the table and the amplitude represented the number that the transmitter wanted to convey. For example, a wave with the amplitude of 60 cm would mean that the number was 60. (Numbers were in increments of 10). Once we completed all the activities, it was clear to see that digital signals were easier to interpret because there were only two options, 1 and 0, compared to the six options of analog.
XCC-Cause and Effect: While learning about the pros and cons of digital and analog technology, I noticed cause and effect relationships. Some of these relationships include the editing process and equipment. Due to digital technology editing went from being a tedious and tiresome task to an efficient and enjoyable job. With digital technology, you can seamlessly edit bits of music and fix hissing, pitch, and nuisance background noises. However, this has caused musicians to rely on a computer rather than on their ears and talent. Also, with autotune, it can rid music of unwanted sound, but makes music sound "too clean and perfect."As for equipment, it is much more presentable and takes up less space making it easier to store, but this has increased its price and made it quite costly. All in all, there are many things that make digital music great, but those benefits do cause some drawbacks.
Multiplier: This week I was a mutant to be more specific a wanderer because I shared what I found with my team during the activities.
