The correct answer is: B. Differential amplifier
A differential amplifier is an electronic amplifier that amplifies the difference between two input signals. It is commonly used in biomedical applications because it is very sensitive to small changes in voltage. Differential amplifiers are also used in other applications, such as audio amplifiers, radio receivers, and data acquisition systems.
A single-ended amplifier is an electronic amplifier that amplifies a single input signal. It is less sensitive to noise than a differential amplifier, but it is not as accurate. Single-ended amplifiers are commonly used in audio amplifiers and radio receivers.
An inverting operational amplifier is an electronic amplifier that inverts the polarity of its input signal. It is commonly used in circuits that require a negative feedback signal. Inverting operational amplifiers are also used in other applications, such as filters, oscillators, and voltage regulators.
A chopper amplifier is an electronic amplifier that uses a chopper to convert an analog signal to a digital signal and then back to an analog signal. This process helps to reduce noise and improve the accuracy of the amplifier. Chopper amplifiers are commonly used in high-precision applications, such as data acquisition systems and medical imaging equipment.
