Poles and Zeros of Network Function: All the Poles and Zeros of Network Function have the form of a ratio of two polynomials in s as, The P(s) is the numerator polynomial in s having…
Programming Techniques in Microprocessor 8085: We have seen the instruction set of 8085 and some simple assembly language programs using it. We know that, the program is an implementation of certain logic by executing group…
Load Capacitance Effect: Capacitance connected at the output of an operational amplifier is termed Load Capacitance Effect (CL). Figure 15-20 shows that CLÂ is in series with the op-amp output resistance (ro), so CL and ro…
Apparent Power and Power Factor: Apparent Power - The power factor is useful in determining useful power (true power) transferred to a load. The highest power factor is 1, which indicates that the current to…
Speed Control of DC Motor Drives: The Speed Control of DC Motor Drives can be any of the following methods: Armature voltage control Field flux control Armature resistance control Speed-torque curves of dc motors for…
Solid State Relay Interfacing: To avoid the problems of mechanical relays, Solid State Relay Interfacing are used. In this triac is used as a switching element and isolation is provided by opto isolators or pulse…
Diesel Electric Traction System: Because of high initial cost, electric traction is justified only where there is sufficient volume of traffic. Diesel Electric Traction System is preferable where the traffic is limited. Boundary between these…
Various Systems of Power Transmission: It has already been pointed out that for transmission of electric power, 3-phase, 3-wire a.c. system is universally adopted. However, other systems can also be used for transmission under special…
Ebers Moll Model for PNP Transistor: Device modelling aims at relating physical device parameters to device terminal characteristics. Device modelling is especially important for integrated circuits, since simple and accurate device models are required to…
Nyquist Criterion: Nyquist Criterion - This stability criterion enables one to establish the stability of a system using a graphical procedure in the frequency domain. Here also there is no necessity for the evaluation of…
