A function generator is an electronic device used to generate electrical waveforms over a wide range of frequencies. It is widely used in the fields of electronics, communications, and testing to create specific signals for testing, calibration, and experimentation. Figure 1: Block diagram of a function generator.
A toggle switch is a type of electrical switch that is operated by moving a lever or handle back and forth to open or close a circuit. Toggle switches are commonly used in various electronic devices and equipment to control electrical power or signal flow. They are reliable, easy to use, and versatile, making them

It is possible to apply more than one input signal to an inverting amplifier. This circuit will then add all these input signals to produce their addition at the output. Such a circuit will then be called as an adder or a summing amplifier.
The voltage gain of the Voltage Follower (Buffer) circuit is 1 i.e. the output voltage will be equal to and in phase with the input voltage. In other words, the output voltage follows the input voltage. Hence the name voltage follower. Thus voltage follower is a non-inverting amplifier with a voltage gain of unity. Figure
In Inverting Amplifier, the amplified output signal will be 180º out of phase with the input signal. In other words the output signal is “inverted” as shown in Fig. 2. Therefore this amplifier is known as the inverting amplifier. Figure 1: Inverting Amplifier.
