A diode is a two-terminal, electronic device made using semiconductors that is designed to prevent current from flowing in a particular direction. The symbol is a triangle pointing in the direction that (positive) current is allowed to flow and a wall preventing (positive) current from flowing in the opposite direction: 1: A diode has two modes, "on" and "off". When "on", current flows, and when "off", no current flows. We generally view diodes as either "ideal" or "modeled", as described below. "Ideal" view of a diode + The "ideal" diode is either a short circuit or an open circuit. Specifically, when the voltage across its terminals is negative, no current flows, and when current flows, there is zero voltage across its terminals, as pictured below: Diode "Modeled" view of a diode +51 Diode V Ideal Diode "Off" i=0| + U≤0 + I Therefore, with current i and voltage v defined as shown on the left above, for an "ideal" diode: • Current i cannot be negative. Voltage v cannot be positive. .…

A voltage-controlled oscillator (VCO) is an oscillator that oscillates at a constant frequency and is controlled by an external bias voltage. A VCO's output is a frequency, and its input is a bias or control signal, which can be either dc or ac voltage. Which of the following assertions is a TRUE statement? Select your answer. The output frequency changes or deviates accordingly when ac voltage is applied to the VCO input. The output frequency changes or deviates appropriately when a square voltage is delivered to the VCO input. The output frequency changes or deviates appropriately when a DC voltage is delivered to the VcO input. The output frequency fluctuates or deviates accordingly when a dc or slowly shifting ac voltage is introduced to the VCO input.
