... Single supply design (Vcc = 5V) was required to power the circuit components. Transduction The CdS cell changes resistance in response to the amount of light it receives. To work with this signal requires that it is transduced into a voltage. The CdS cell was placed in series with a 47 KOhm resistor ...

... For the denominator, those can be combined into a single complex number. 19+1 is 20. x+5 is the imaginary part. The magnitude should be the real part squared plus the imaginary part squared. 380 divided by 400 is 19/20, which is equal to 0.95. Let’s take the square of both sides of the equation. [eq ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
