Недостатки
В некоторых случаях цифровые схемы используют больше энергии, чем аналоговые для выполнения одной и той же задачи, выделяя больше тепла, что повышает сложность схем, например, путём добавления кулера. Это может ограничить их использование в портативных устройствах, питающихся от батареек.
Например, сотовые телефоны часто используют маломощный аналоговый интерфейс для усиления и настройки радио-сигналов от базовой станции. Тем не менее, базовая станция может использовать энергоемкую, но очень гибкую программно-определяемую радиосистему. Такие базовые станции можно легко перепрограммировать для обработки сигналов, используемых в новых стандартах сотовой связи.
Цифровые схемы иногда дороже аналоговых.
Возможна также потеря информации при преобразовании аналогового сигнала в цифровой. Математически это явление может быть описано как ошибка округления.
В некоторых системах при потере или порче одного фрагмента цифровых данных может полностью измениться смысл больших блоков данных.

DisadvantagesIn some cases, digital circuits use more energy than analog to perform the same tasks, allocating more heat, which increases the complexity of the schemes, for example, by adding cooler. This can limit their use in portable devices, from batteries.For example, cell phones often use low-power analog interface to enhance and customize the radio signals from the base station. However, the base station can use energy-intensive but very flexible software-defined radio. These base stations can be easily reprogrammed to handle signals used in new cellular standards.Digital circuits are sometimes more expensive than analog.It is also possible information loss when converting an analog signal to digital. Mathematically it can be described as a rounding error.In some systems, when the loss or corruption of a single piece of digital data can completely change the meaning of large blocks of data.

It is also possible loss of information when converting analog signals to digital. Mathematically, this phenomenon can be described as a rounding error.
In some systems, the loss of or damage to one piece of digital data can completely change the meaning of large blocks of data.
