Digital signals
(`i`) do not provide a continuous set of values.
(`ii`) represents values as descrete steps.
(`iii`) can utillize binary system
(`iv`) can utillize decimal as well as binary system.
The true option is.

Options

A. Only (i) and (ii)
B. Only (ii) and (iii)
C. (i),(ii) and (iii), but not (iv)
D. All the above (i) to (iv)

Answer

To solve the question regarding the characteristics of digital signals, we will analyze each statement one by one.

### Step 1: Analyze Statement (i)
**Statement:** Digital signals do not provide a continuous set of values.

**Analysis:** This statement is true. Digital signals represent information in discrete values rather than a continuous range. This is a fundamental characteristic of digital signals.

### Step 2: Analyze Statement (ii)
**Statement:** Digital signals represent values as discrete steps.

**Analysis:** This statement is also true. Digital signals are defined by specific levels or steps, meaning they can only take on certain values, not a continuous spectrum.

### Step 3: Analyze Statement (iii)
**Statement:** Digital signals can utilize binary system.

**Analysis:** This statement is true as well. Digital signals are typically represented in binary form, using two states (0 and 1). This is a key feature of digital communication.

### Step 4: Analyze Statement (iv)
**Statement:** Digital signals can utilize decimal as well as binary system.

**Analysis:** This statement is false. While digital systems can represent numbers in various bases, the fundamental representation of digital signals is binary (0s and 1s). Decimal representation is not typically used for the transmission of digital signals.

### Conclusion
Based on the analysis:
- Statements (i), (ii), and (iii) are true.
- Statement (iv) is false.

Thus, the correct options are (i), (ii), and (iii).

### Final Answer
The true options are (i), (ii), and (iii). Therefore, the correct answer is option C.
