Analysis and reconstruction of ECG wave from sampled data is an important aspect in estimating the physiological condition of heart as well as in transmitting the ECG data to a remote location. In the present paper software based off line Fourier analysis technique has been reported to find the harmonic components of ECG wave of a normal subject. The(More)
A thyristor driven pump is operated by varying the DC input signal in the firing circuit of thyristor drive. This operation suffers from difficulties due to the nonlinear relation between thyristor output and DC input. In the present paper, an opto-isolator based linearization technique of a typical thyristor driven pump has been proposed. The design,(More)
In the present paper, design of a flow control loop using a thyristor driven pump as final control element has been described. In this technique, the load current of a thyristor driven pump motor has been utilized as a mass flow sensing parameter of a fluid passing through a pipeline. This thyristor driven pump has been utilized as a final control element(More)
