The filter whose transfer function is of the form $G\left(s\right)=\frac{s^2-bs+c}{s^2+bs+c}$ is

Let 3 + 4j be a zero of a fourth order linear-phase FIR filter. The complex number which is NOT a zero of this filter is

Consider the ammeter-voltmeter method of determining the value of the resistance R using the circuit shown in the figure. The maximum possible errors of the voltmeter and ammeter are known to be 1% and 2% of their readings, respectively. Neglecting the effects of meter resistances, the maximum possible percentage error in the value of R determined form the measurements, is _________ %.

The bridge most suited for measurement of a four-terminal resistance in the range of 0.001 Ω to 0.1 Ω is

A power line is coupled capacitively through various parasitic capacitances to a shielded signal line as shown in the figure. The conductive shield is grounded solidly at one end. Assume that the length of the signal wire extending beyond the shield, and the shield resistance are negligible. The magnitude of the noise voltage coupled to the signal line is
