Which of the following functions is not performed by a signal conditioner? Correct Answer Noise addition

Signal Conditioner:

A signal conditioner is a circuit that manipulates the signal so that it meets the requirement (current and voltage levels) of the next stage for further processing.

Most commonly Analog to Digital Converters are used for signal processing

Steps Involved in Signal Conditioning are:

  1. Filtering: To remove the unwanted frequency and noise
  2. Amplification: increase the resolution and increase signal to noise ratio
  3. Attenuation: Attenuation, the opposite of amplification, is necessary when voltages to be digitized are beyond the ADC range

Consider the following statements regarding modulation : 1. The communication systems, where a weak signal is transmitted by the use of a modulation is essential in carrier signal. 2. When the frequency of the high frequency signal is varied in accordance with the intensity of the low-frequency weak signal, the modulation is said to be frequency modulation. 3. The process of recovering original baseband signal from the modulated signal is called phase modulation. Which of the above statements are correct ?

Consider the following solution to the producer-consumer synchronization problem. The shared buffer size is ?. Three semaphores empty, full and mutex are defined with respective initial values of 0, ? and 1. Semaphore empty denotes the number of available slots in the buffer, for the consumer to read from. Semaphore denotes the number of available slots in the buffer, for the producer to write to. The placeholder variables, denoted by P, Q, R, and S, in the code below can be assigned either empty or full. The valid semaphore operations are: wait ( ) and signal ( ). Producer: Consumer: do {         wait (P) ;         wait (mutex) ;         //Add item to buffer         signal (mutex) ;         signal (Q) ; } while (1) ; do {          wait (R) ;          wait (mutex) ;          //Consume item from buffer          signal (mutex) ;          signal (S) ; } while (1) ;   Which one of the following assignments to P, Q, R and S will yield the correct solution?
