do anyone know the equation I have to use to solve this problem? this have to do with the On-Off keying and ASK modulation.

can someone help me do this and maybe also the picture of the
scope explain how you get it. thankyou!
Frequency-shift keying (FSK) and Phase-shift keying (PSK) Two other modulation schemes are the phase-shift keying (PSK) and the frequency-shift keying (FSK). These are illustrated in Figure 8 b and c respectively. In phase-shift keying the carrier signal changes phase by a radians when the digital signal changes values. In frequency-shift keying a 0 is transmitted at a different carrier frequency...

QUESTION 3 Briefly explain the following Analog Pulse Modulation (APM): (i) Pulse Amplitude Modulation (PAM) Pulse Width Modulation (PWM) (iii) Pulse Position Modulation (PPM) (2 marks) (2 marks) (2 marks) b) There are several digital modulations techniques used to modulate digital signal. For a binary data 10111011, sketch the output waveform if the following modulator is used: Amplitude Shift Keying (ASK) (2 marks) Frequency Shift Keying(FSK) (2 marks) (iii) Phase Shift Keying (PSK)...

1. 145 points) <FM/FSK Modulation/Demodulations A periodic wave m(t) in Figure 1 below The resulting FM signal is demodulated as shown in the following figure by using frequency discriminator. Assume no attenuation of the signal due to propagation loss (in other words assume amplifiers properly restored the amplitude of the transmitted signal at the receiver) [10 points] Find the Fourier Series (trigonometric Fourier Series) of the message signal m (t) where To...
The technique sometimes used to make an information signal compatible with the medium over which it is being transmitted is called? ModulationWhat is the name given to undesirable interference that is added to a signal being transmitted? NoiseName the technique used to extract multiple intelligence signals that have been transmitted simultaneously over a single communication channel. MultiplexingIn the electromagnetic wave spectrum, the frequency of radio waves ranges from...
Hi everyone, I have a question about active filter, including a
simulation,
Please provide the screen capture.
Thanks.
5. Active Filter - III Consider the RC op-amp circuit shown in Fig. 5.4. Vin(t) is a sinusoidal signal with Vpp = 1 V, Rı = 10 ㏀ , R, = 20 ㏀ , and C,-C,-0.01 μF. Use Vcc-15V, The capacitors have zero initial energy stored. Ri 741 C1 C2 Volt) Fig. 5.5: Active filter - III (a) Find the transfer function...

this!
(1) Write a program to combine 2 (two) waves with different frequencies (fm and fc) using AM (Amplitude Modulation) technique: y(t) = [1 + m cos(2 π fn t) ] A sin(2 π ) where fm is the modulated frequency, fc is the carrier frequency, A- Amplitude, m- index of modulation, t time and 3.14159265359 (A) Plot y(t) in time domain t = 0 to...
DC-AC inverters have many commercial and residential applications, including uninterruptible power supply (UPS) units, adjustable speed drives (ASD) for AC motors, and electronic frequency changer circuits. They are also used in solar electrical systems where batteries are charged from solar panels and used as the input DC voltage source. The inverter circuit converts the DC into AC voltage of desired frequency. Most of us are also familiar with HVDC transmission systems, where high voltages are first converted from AC to...
