FM Waveform Generator Standard: Frequency Modulation (FM) Message Frequency (Hz) 50 Hz Carrier Frequency (Hz) 500 Hz Kf (frequency sensitivity): 50 Step 1: messagePlot $m(t) = A_m\cos(2\pi f_m t)$ Step 2: carrierPlot $c(t) = A_c\cos(2\pi f_c t)$ Step 3: superimposed $x(t) = [c(t) + m(t)]$ Step 4: modulatedPlot $s(t) = A_c\cos\left(2\pi f_c t + 2\pi k_f\int m(t)\,dt\right)$ Perform FM Demodulation Return to Premium Virtual DSP Lab → ...

Amplitude Demodulation Instructions for Amplitude Modulation (AM) Step 1: Click on 'Generate Message' button to generate input message signal Step 2: Then click on 'Generate Carrier' button to generate carrier signal. The carrier frequency has to be more than the message frequency and You can change frequencies using sliders Step 3: Click on 'Generate Amplitude Modulated Signal' button to generate Amplitude Modulated Signal Step 4: Click the 'Show Frequency Spectrums' button to view the AM spectra. Here, the modulation index is defined as the ratio of the message signal amplitude to the carrier signal amplitude. You can adjust both values. 50 Hz Step 1: Generate Message 500 Hz ...

  Is India’s Telecom Pricing Becoming a Burden for the Common Man? Every few months, we see changes in mobile plans, pricing, and affordable recharge options. For an individual, ₹20–₹50 may seem like a small amount. But for a family with multiple connections, the impact adds up every month. Today, mobile connectivity is essential—not a luxury. UPI, banking, education, jobs, government services, and even emergency communication depend on it. Telecom companies have every right to grow and earn profits. But the question is: Where should the balance be between business growth and consumer affordability? If prices continue to increase while cheaper options disappear, the burden ultimately falls on ordinary families. This is not just about Airtel. It is about the affordability of essential digital connectivity in India. Why Is Mobile Data Becoming More Expensive in India? Mobile data and recharge prices in India have been trending upward...
