Which of the following four properties are possessed by the system? BIBO: Bounded input gives a bounded output
Causal: The system is causal.
LP : The system is low pass.
LTI: The system is linear and time-invariant.
The ‘Envelope delay’ or ‘Group delay’ is the time delay that the signal component of frequency ω undergoes as it passes from the input to the output of the system.
Following waveform shows the output B of a buffer having delay 10 ns for two different delay mechanisms, specify the name of delay mechanism for corresponding waveform.
The input to a channel is a bandpass signal. It is obtained by linearly modulating a sinusoidal carrier with a single-tone signal. The output of the channel due to this input is given by
$$y\left( t \right) = \left( {{1 \over {100}}} \right)\cos \left( {100t - {{10}^{ - 6}}} \right)\cos \left( {{{10}^6}t - 1.56} \right)$$
The group delay (tg) and the phase delay (tp) in seconds, of the channel are
The output signal when a signal x(n)=(0,1,2,3) is processed through an ‘Identical’ system is?
Wages of the workers are normally, the proportionality derived from their efficiency. But the concept of efficiency of labour is itself vague such as amount of physical output, output per man hour or output per man shift. But output is not the function of man alone. There are other factors which affect the output. Which among the following is/are not the factor(s) that would affect the output directly?
1. Physical condition of work
2. Nature of machinery
3. Technical process
4. Quality of raw material
5. System of management
6. Role of fellow workers
7. Competitors in the market

A buffer with single input A and single output B has a delay of 20 nanosecond. If the value of input A changes after 10 ns from 0 to 1 and it changes again from 1 to 0 at 20 ns. At what time, the value of output B will be 1, if the inertial delay model is used?
