Objective:

• Observe the different signals are transmitted in a given band width by using the different carrier frequencies 

  • Recovery of modulating signal by selecting the various carrier frequencies using band pass filters and separate Detectors 

Technical Specifications : 

• In built IC based DC regulated power supply ±12V/500mA

• On board sine wave audio frequency signal generator 

Frequency: 1KHz & 2KHz                      Amplitude: 0-2VppApprox,

• On board carrier's signal generator sine wave 

Frequency: 60KHz & 40KHz                  Amplitude' 5Vpp & 5Vpp Approx.

• Modulation using balanced modulator using IC 1496 followed by an adder using IC Tl081

• Demodulation using balanced modulator using IC 1496, band pass filter using IC TL081 followed by low pass filter

• Glass Epoxy PCB used as front panel 

Optional Accessories : 

Dual Trace CR0 20MHz
