Time Division Multiplexing(TDM): Time Division Multiplexing - Any pulse modulation scheme involves translating the audio, or modulating signal into a series of encoded pulses, sending these pulses over a transmission…
Data Logger Operation: Data Logger Operation - For proper understanding of a Data Logger Operation, it is essential to understand the difference between analog and digital signals. For example, measurement…
Weighted Converter Using Transistor Switches (Current Switch): Figure 17.19 (a) shows a circuit diagram of a weighted converter, using transistor switches. When the D bit is high (logic 1), it…
Binary Ladder Circuits: A Binary Ladder Circuits is constructed of resistors having only two values and thus overcomes the disadvantages of weighted resistors. The left end of the ladder is…
Ladder Type Converter D/A: Looking into any load from the left side we always see a resistor R. Similarly looking from the right side for any load, one always sees…
Variable Resistor Network: Variable Resistor Network - The basic problem in converting a digital signal into an equivalent analog signal is to change the n digital voltage levels into one…
Signal Conditioning of Inputs: Since all the data that have to be acquired, do not generally originate from identical sources, signal conditioning becomes necessary in some cases. A simple attenuator,…
Sensitivity Measurement Definition: The Sensitivity Measurement Definition of a radio receiver is its ability to amplify weak signals. It is often defined in terms of the voltage that must be…
