For the signal shown, which of the following represents its inverted waveform? Correct Answer <img alt="F1 Shraddha Shubham 02.06.2021 D10" src="//storage.googleapis.com/tb-img/production/21/06/F1_Shraddha_Shubham_02.06.2021_D10.png" style="width: 154px; height: 18px;">

Concept:

In the representation of digital signals, we use the two symbols to represents the corresponding analog voltages.

Logic '1' → Higher voltage level

Logic '0' → Lower voltage level

There are two types of representation of these levels.

  1. Positive logic
  2. Negative logic

In the inverted form of the waveform, the logic '1' is transformed to logic '0' and vice-versa.

Calculation:

Consider the given waveform:

Time Original Waveform Inverted waveform
0 to t1 1 0
t1 to t2 0 1
t2 to t3 1 0
t3 to t4 0 1
t4 to t5 1 0
t5 to t6 0 1
t6 to t7 1 0

 

The inverted waveform can be represented as:

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?

Study the given bar graph and answer the question that follows. The given bar graph represents the Sales Turnover (in Rs.  crore) of five automobile companies A, B. C, D and E during 2014-2015 and 2015-2016. The X-axis represents the Companies, and the Y-axis shows the Sales Turnover (in Rs. crore). (The data shown here is only for mathematical exercise. They do not represent the actual figures of the company.) What should have been the sales turn over (in Rs. crore) of Company C in 2015-2016 to have shown the same increase in its sales over 2014-2015 as shown by the sales turnover of Company E?
