Modem Definition: The term Modem Definition is an acronym for modulator-demodulator. The primary modem function is to convert digital data into an analog form which is suitable for transmission on…
Delta Modulation(DM): Delta modulation(DM) is process of modulation in which train of fixed width pulses is transmitted. Their polarity indicates whether the demodulator output should rise or fall at each…
Data Logger Summary: In general, a data logger is a comprehensive and highly advanced Data Logger Summary. It is made versatile and flexible, to render it suitable for widely varying…
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…
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…
Single Channel Data Acquisition System: A Single Channel Data Acquisition System consists of a signal conditioner followed by an analog to digital (A/D) converter, performing repetitive conversions at a free…
Radio Frequency Modulation: Radio Frequency Modulation - The simplest method of measuring frequency deviation utilises an FM receiver with a BFO as the measuring instrument. The only coupling used is…
Modulation Frequency Definition: Modulation Frequency Definition is the process of impressing information on a carrier wave by altering either its amplitude of frequency. In amplitude modulation, the degree is the…
