How to Use MC1496 Balanced Modulator in Proteus

How to Use MC1496 Balanced Modulator in Proteus

MC1496 is a versatile integrated circuit that can perform both modulation and demodulation of signals. It can be used for amplitude modulation (AM), frequency modulation (FM), phase modulation (PM), and other applications. However, MC1496 is not available in the default library of Proteus, a popular software for circuit simulation and design. In this article, we will show you how to add MC1496 to Proteus and use it in your projects.

Step 1: Download MC1496 Library File

The first step is to download the library file for MC1496, which contains the schematic symbol and the simulation model of the chip. You can find the library file from this link: https://hub.docker.com/r/tmanzasobulk/proteus-mc1496-lib. Alternatively, you can create your own library file by following the instructions in this video: https://www.youtube.com/watch?v=Ja8hUwZJreY.

Step 2: Copy MC1496 Library File to Proteus Folder

The next step is to copy the library file to the Proteus folder, where all the other library files are stored. The default location of the Proteus folder is C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY. Paste the library file in this folder and restart Proteus.

Step 3: Search and Add MC1496 to Your Circuit

Now you can search and add MC1496 to your circuit in Proteus. To do this, open Proteus and click on the P button on the toolbar. This will open the Pick Devices dialog box, where you can search for any component by name or keyword. Type MC1496 in the search box and press Enter. You should see MC1496 appear in the list of devices. Select it and click OK. You can now place MC1496 on your schematic and connect it with other components.

Step 4: Configure MC1496 Parameters

The last step is to configure the parameters of MC1496 according to your needs. To do this, double-click on MC1496 on your schematic and open the Edit Component dialog box. Here you can change the values of various parameters, such as carrier frequency, modulation index, input impedance, output impedance, etc. You can also choose between different modes of operation, such as balanced modulator, suppressed carrier modulator, product detector, etc. Click OK when you are done.


In this article, we have shown you how to use MC1496 balanced modulator in Proteus. MC1496 is a useful chip that can perform various modulation and demodulation functions. However, it is not included in the default library of Proteus, so you need to download or create a library file for it and copy it to the Proteus folder. Then you can search and add MC1496 to your circuit and configure its parameters as desired. We hope this article was helpful for you.

Example Circuit Using MC1496

To illustrate how MC1496 works, let us consider an example circuit that uses MC1496 as a balanced modulator. The circuit is shown below:

In this circuit, MC1496 is connected to a carrier signal generator, a message signal generator, and an oscilloscope. The carrier signal generator produces a sinusoidal signal of 10 kHz frequency and 5 V peak-to-peak amplitude. The message signal generator produces a sinusoidal signal of 1 kHz frequency and 1 V peak-to-peak amplitude. The oscilloscope displays the input and output signals of MC1496.

The operation of MC1496 as a balanced modulator can be explained as follows: The carrier signal is applied to pins 1 and 4 of MC1496, which are the carrier inputs. The message signal is applied to pins 10 and 11 of MC1496, which are the signal inputs. The output of MC1496 is taken from pins 6 and 12, which are the differential outputs. The output signal is a modulated signal that contains the sum and difference frequencies of the carrier and message signals. The output signal has a suppressed carrier component, which means that the carrier frequency is not present in the output signal. The output signal has a modulation index of 0.5, which means that the amplitude of the sidebands is half of the amplitude of the carrier.

Testing the Performance of MC1496

To test the performance of MC1496, we can use some metrics such as modulation depth, distortion, noise, and power consumption. Modulation depth is a measure of how much the carrier amplitude varies with the message amplitude. Distortion is a measure of how much the output signal deviates from the ideal modulated signal. Noise is a measure of how much unwanted signals are present in the output signal. Power consumption is a measure of how much electrical energy is used by MC1496.

We can use Proteus to measure these metrics by using various tools and instruments. For example, we can use the Spectrum Analyzer tool to measure the modulation depth and distortion of the output signal. We can use the Noise Generator tool to add noise to the input signals and see how it affects the output signal. We can use the Power Meter tool to measure the power consumption of MC1496.

Advantages and Disadvantages of Using MC1496

MC1496 has some advantages and disadvantages when compared to other modulation and demodulation methods. Some of the advantages are:

  • MC1496 is a versatile chip that can perform various modulation and demodulation functions with simple external components.

  • MC1496 has a high input impedance and a low output impedance, which makes it easy to interface with other circuits.

  • MC1496 has a wide operating frequency range, which makes it suitable for various applications.

Some of the disadvantages are:

  • MC1496 requires a balanced carrier input and a balanced signal input, which may require additional circuits to generate or convert them.

  • MC1496 has a limited modulation depth, which may affect the quality of the output signal.

  • MC1496 has a relatively high power consumption, which may affect the battery life of portable devices.
