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.
First are dose-response studies. The dose of trazodone needed to induce and maintain sleep is not well understood. Thus, clinicians use anywhere from 25 mg to 150 mg taken at bedtime as a hypnotic dose. This is a critical question because it is recognized that at high doses these medications carry a high safety risk.
