Sampling

The signal that is fed to an A/D converter should be maintained constant during the conversion period. In case of an A.C.

RC Low-pass Filter Circuit

Fig. 1 shows the series RC low pass filter circuit. This circuit is identical with that of high-pass filter circuit except for the fact that the output is now taken across

Ramp Generators

Voltage and current linear ramp generator find wide application in instrumentation and communication systems. Linear ramp generators are also known as sweep generators

Oscillators

An oscillator is an electronic device for generating an AC signal voltage. Oscillators generate sinusoidal or non-sinusoidal waveforms from very low frequencies

Monostable Multivibrators

In a monostable multivibrator, one of the state is absolutely permanent i.e, stable and the other one is temporary i.e, quasi-stable.

Intel 8085 8-bit Microprocessor

Intel 8085 is an 8-bit, NMOS microprocessor. It is a 40 pin C package fabricated on a single LSI chip. The Intel 8085A uses a single +5V D.C supply for its operation.

Instruction Set of Intel 8085 Microprocessor

An Instruction is a command given to the computer to perform a specified operation on given data. The instruction set of a microprocessor is the collection of the instructions that the microprocessor is designed to execute.

Flip Flops

A digital computer needs devices which can store information. A flip flop is a binary storage device. D flip flop, jk, T, Master Slave
