Signals and Amplifiers topics include: The basics of signals, amplifiers, sinusoidal steady state analysis, amplifier circuit models and frequency response. A signal amplifier is a circuit that uses electrical power to increase the amplitude of an incoming signal voltage or current signal. The output terminals of the signal amplifier output the higher amplitude version. Here are some types of amplifiers: Small signal amplifiers: Also called voltage amplifiers, these amplifiers amplify an input voltage to a higher output voltage. However, the output may not have enough power to drive loads...

A signal amplifier is a circuit that uses electrical power to increase the amplitude of an incoming signal voltage or current signal. The output terminals of the signal amplifier output the higher amplitude version. Here are some types of amplifiers: Small signal amplifiers: Also called voltage amplifiers, these amplifiers amplify an input voltage to a higher output voltage. However, the output may not have enough power to drive loads like motors and loudspeakers. Power amplifiers: This subtype of amplifier raises the power of a signal. They are used in modern consumer electronic devices such as smartphones and tablets. RF amplifiers: These tuned amplifiers convert the input signal into an output signal that provides the required response at a given frequency. Differential amplifiers: These amplifiers amplify the difference of the two signals applied to its input. They are subtractor circuits that subtract the two applied input and then produce amplified output. Current amplifiers: These amplifiers increase the current of an input signal. They are often used in power electronic systems, such as in power supplies or motor controllers. Transistor amplifiers: These amplifiers are fully reliant on transistors. They can use a current, voltage, or power signal as the input signal. The signal is amplified without affecting its properties, and the output is a modified version of the original signal. Show less
