(a)State four properties of an ideal operational amplifier. In each case explain the significance of the property to the practical operational amplifiers. (b)Consider the following Op Amp circuit in Figure

4.1. i)Identify the type of this basic operational amplifier circuit. ji)Calculate the gain of this amplifier. iii)Calculate the value of RF if the Ri is 1KOHMS to give a gain of 10. The following signal shown in Figure 4.2 is then applied to VIN in Figure 4.1.Sketch the output waveform (VOUT) for the Op Amp design in question number (iii). (Assume supply voltage is ±15V)
