How is a Hartley Oscillator identified? -Correct Answer ✔They have two inductors in the
feedback circuit.
How is frequency determined in a Hartley Oscillators? -Correct Answer ✔The values of
the components in the feedback circuit determine the frequency.
How is a colpitts oscillator identified? -Correct Answer ✔Two capacitors in the feedback
circuit.
How is frequency determined in a colpitts oscillator? -Correct Answer ✔Frequency is
determined by the components in the feedback circuit.
How is an RC Phase Shift oscillator identified? -Correct Answer ✔They have three RC
networks in the feedback circuit.
What is the total phase shift in an RC Phase shift oscillator? -Correct Answer ✔360
degrees.
Q1 is a common emitter amplifier that produces a 180 degree phase shift. Each RC
network produces a phase shift as well.
How is frequency determined with the sawtooth oscillator? -Correct Answer ✔The
frequency of the output is determined by the frequency of the input.
What is the purpose of a blocking oscillator? -Correct Answer ✔They change DC into
short, rectangular pulses that can be used as timing pulses to trigger other circuits.
Blocking Oscillator -Correct Answer ✔Any oscillator that cuts off its own oscillations at a
predetermined time.
Transconductance (gm) -Correct Answer ✔The amount of control that the input voltage
has over the output current.
