Analog Circuits Unit

The Analog Circuits Unit, allows the student to learn the most important concepts of different electronic circuits: analog multiplexer, analog multiplier, function generator, AM modulator and AM demodulator.

ATENG 11279 — Analog Circuits Unit

• The “ATENG 11279” unit mainly consists of:
  Analog Multiplexer. It allows the user to select between two analog signals. There is a digital control signal for selecting the input signal.
• Two input signals.
• Input Voltage: ±10 V max.
• TTL compatible control signal.
  Analog Multiplier. Includes a potentiometer to control the gain of the multiplier.
• Two input signals.
• Input Voltage: ±10 V max.
• Function Generator. It allows the user to generate three different signals types: sinusoidal, square and sawtooth. The frequency and
  amplitude of the signals can be adjusted using the potentiometers.
• Sine, square and sawtooth signals.
• Amplitude: ±10 V.
• Frequency: 0 Hz – 100 Hz.
  AM Modulator. It allows the user to generate an AM signal. The frequency of the carrier signal can be selected by using a potentiometer.
• AM-DSB modulator.
• Carrier frequency: 1000 Hz max.
• AM Demodulator. It allows the user to demodulate an AM signal. The demodulator is divided in different blocks: mixer, IF amplifier,
  envelope detector and audio filter. The frequency of the local oscillator generated for the tuning can be selected by using a potentiometer.
  All outputs of these blocks can be observed using the output terminals.
• Tuning circuit.
• IF amplifier (455 Hz).
• Envelope detector.
• Audio signal filter.
• DC source module:
• +/- 12 VDC.
• +/- 5 VDC.
  Cables and accessories, for normal operation.
