Differentiate simple ACC and delayed AGC in terms of feedbackvoltage, threshold voltage level and receiver gain only.

To differentiate between simple Automatic Contrast Control (ACC) and delayed Automatic Gain Control (AGC) in terms of feedback voltage, threshold voltage level, and receiver gain, we need to understand the functions and characteristics of each.

1. Feedback Voltage:

   • Simple ACC: In simple ACC, the feedback voltage is used to adjust the contrast of the display. It is typically derived from the output signal and compared to a reference voltage to determine the necessary adjustment.
   • Delayed AGC: In delayed AGC, the feedback voltage is used to control the gain of the receiver circuit. It is typically derived from the output signal and compared to a reference voltage to adjust the gain accordingly.

2. Threshold Voltage Level:

   • Simple ACC: The threshold voltage level in simple ACC determines the point at which the contrast adjustment is triggered. When the feedback voltage exceeds this threshold, the contrast adjustment is activated.
   • Delayed AGC: The threshold voltage level in delayed AGC determines the point at which the gain adjustment is triggered. When the feedback voltage exceeds this threshold, the gain of the receiver circuit is adjusted.

3. Receiver Gain:

   • Simple ACC: The receiver gain in simple ACC remains constant. The focus is on adjusting the contrast of the display, rather than the gain of the receiver circuit.
   • Delayed AGC: The receiver gain in delayed AGC is adjustable. The feedback voltage is used to control the gain of the receiver circuit, ensuring optimal signal reception and amplification.

In summary, the main difference between simple ACC and delayed AGC lies in their respective functions and applications. Simple ACC focuses on adjusting the contrast of the display, while delayed AGC focuses on controlling the gain of the receiver circuit. The feedback voltage, threshold voltage level, and receiver gain are utilized differently in each system to achieve their specific objectives.
