Analog Electronics Process Controllers: An Analog Electronics Process Controllers must be capable of providing one or more of the three main methods of control, namely, Proportional, Integral and Derivative. The…
Step Function Response: The step function response consists of applying an instantaneous change in the control means and then recording graphically the result of the change on the measured variable.…
Heat Capacity of Calorimeter: Heat Capacity of Calorimeter - RF power may be directly converted into heat. Water acts as the load, and RF power may be used to heat…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
Precision Frequency Standard: Most high precision frequency standard in use utilise a geometric transverse (GT) cut quartz crystal as the frequency controlling resonant elements having changes in frequency of less…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
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…
Compact Data Logger: Compact Data Logger - A typical unit provides 60 channels of data in a 20 x 40 x 60 cm box weighing about 20 kg. Most manufacturers…
