Digitization. When an analog waveform is converted to a digital file, the analog information must first be translated into bits. This is done through sampling, a process performed by a computer's Analog to Digital Converter (ADC) hardware.
For example, the drowsiness effect of trazodone can be helpful for people who have insomnia. Trazodone is especially useful as a sleep aid in people with depression, since it is effective for both insomnia and depression. Conversely, some antidepressants are likely to cause insomnia, even when taken in the morning. Trazodone can be used to treat insomnia caused by other antidepressant medications.
Trazodone works by preventing serotonin from being reabsorbed back into the nerve cells in the brain. It may also mimic the mood-lightening effect of released serotonin and enhance a very small degree of noradrenaline release from nerve cells in the brain.
