Introduction to circuit characteristics and analysis: resistance, voltage, current, power, a.c. d.c. capacitance, inductance, series and parallel configurations, Ohm's law, Kirchoff's laws, superposition theorem and nodal analysis. Ideal operational amplifier circuits including inverting, non-inverting, comparator, differentiator and the integrator. Analysis of simple LCR networks energised by AC sources. This will inlcude analysis in the time domain and using complex numbers and phasors in the frequency domain. Simplification techniques suitable for both DC and AC analysis such as Thevenin and Source Transformations. Low pass, high pass, band pass and band stop filters
