A band-limited signal with a maximum frequency of 5 kHz is to be sampled. According to the sampling theorem, the sampling frequency in kHz which is not valid is

The differential pressure transmitter of a flow meter using a venturi tube reads 2.5 × 10⁵ Pa for a flow rate of 0.5 m³/s. The approximate flow rate in m³/s for a differential pressure 0.9 × 10⁵ Pa is

A bulb in a staircase has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and also can be turned OFF by any one of the switches irrespective of the state of the other switch. The logic of switching of the bulb resembles

The impulse response of a system is h(t) = t u(t) . For an input u(t - 1) , the output is

The operational amplifier shown in the circuit below has a slew rate of 0.8 volts/μs. The input signal is 0.25 sin(ωt). The maximum frequency of input in kHz for which there is no distortion in the output is
