Multiplexer – Applications & Advantages

The multiplexer is a combinational logic circuit designed to switch one of several input lines to a single common output line by the application of a control logic. The input has a maximum of 2N data inputs (where N = selection or control lines) and single output line. In short, Multiplexer is also known as Mux or data selector or many to … Read more

Full Subtractor – Truth table & Logic Diagram

A subtractor is a digital logic circuit in electronics that performs the operation of subtraction of two number. Subtractors are classified into two types: half subtractor and full subtractor. A full subtractor (FS) is a combinational circuit that performs a subtraction between two bits, taking into account borrow of the lower significant stage. This circuit … Read more

Half Subtractor – Truth table & Logic Diagram

A subtractor is a digital logic circuit in electronics that performs the operation of subtraction of two number. Subtractors are classified into two types: half subtractor and full subtractor. The half subtractor (HS) circuit has two inputs: A and B, which subtract two input binary digits and generate two binary outputs i.e. borrow and difference. Truth table … Read more

Functional Block diagram of Digital Frequency Meter Working principle of Digital frequency meter 1. The unknown frequency signal is fed to the Schmitt trigger. The signal may be amplified before being applied to Schmitt trigger. 2. In a Schmitt trigger, the signal is converted into a square wave with very fast rise and fall times, then … Read more

Data Transmission Media

The data is transmitted from one place to other through different mediums. All transmission system has two devices i.e. transmitting and receiving end devices. These two devices are connected through a medium. there are two types of transmission i.e. Baseband transmission Broadband transmission Baseband transmission When data are sent without modulation, usually over wires or … Read more
