For interfacing the digital circuit with the analog circuit, we must be able to convert the digital signal into an analog signal and analog signal into a digital signal.
R-2R ladder DAC is the most widely used circuit for converting the digital signal into the analog signal. For implementing R-2R DAC we require only two different values of resistors, one is R and other is 2R.
An Operational Amplifier is a high gain direct-coupled amplifier and available in a single integrated circuit package. The operational amplifier is abbreviated to op-amp.
The arrangement of the diode network which has the ability to clip off some portion of the input signal without distorting remaining part is known as diode clippers.
It is an arrangement of diode and capacitor which is used to shift the positive and negative peak of a signal at some desired dc level by not changing the shape of the signa
Actually, this is the circuit of the astable multivibrator. We can make the blinking LED with the help of the astable multivibrator circuit.
