## Threshold Voltage Solution

STEP 0: Pre-Calculation Summary
Formula Used
threshold_voltage = Gate to Channel Voltage-(Channel Charge/Gate Capacitance)
VT = Vgs-(Qchannel/Cg)
This formula uses 3 Variables
Variables Used
Gate to Channel Voltage - Gate to Channel Voltage is the voltage across (Measured in Volt)
Channel Charge - Channel Charge of matter that causes it to experience a force when placed in an electromagnetic field. (Measured in Coulomb)
Gate Capacitance - Gate Capacitance is the capacitance of the gate terminal of a field-effect transistor. (Measured in Farad)
STEP 1: Convert Input(s) to Base Unit
Gate to Channel Voltage: 8 Volt --> 8 Volt No Conversion Required
Channel Charge: 9 Coulomb --> 9 Coulomb No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
VT = Vgs-(Qchannel/Cg) --> 8-(9/4)
Evaluating ... ...
VT = 5.75
STEP 3: Convert Result to Output's Unit
5.75 Volt --> No Conversion Required
5.75 Volt <-- Threshold voltage

## Explain how binary number can give a signal or convert into a digital signal?

The binary number consists of either 0 or 1, in simple words number 1 represents the ON state, and number 0 represents the OFF state. These binary numbers can combine billion of machines into one machine or circuit and operate those machines by performing arithmetic calculations and sorting operations.
