A receiver is operated at a temperature of 300 K. The transistor used ...
The Johnson noise voltage (Vn) can be calculated using the following formula:

Vn = sqrt(4 * k * T * R * B)

Where:
- Vn is the Johnson noise voltage
- k is the Boltzmann constant (1.38 × 10^-23 J/K)
- T is the temperature in Kelvin (300 K)
- R is the resistance in ohms (1 kΩ)
- B is the bandwidth in hertz (200 kHz = 200,000 Hz)

Plugging in the values:

Vn = sqrt(4 * (1.38 × 10^-23 J/K) * (300 K) * (1,000 Ω) * (200,000 Hz))

Vn ≈ 1.8 x 10^-8 volts

So the Johnson noise voltage for the receiver with a bandwidth of 200 kHz is approximately 1.8 x 10^-8 volts.
