How do you do modulation BPSK with a digital input the modulation must use matlab simulink?
Shengks
BPSK Modulation can be done by using a multiplier. Digital data must be multiplied with the carrier frequency. In matlab simulink use a multiplier block to one input apply a sinusoidal generator & to the other a Pulse generator

Is the computer is input or output?
modulation and demodulation
Pulse Position modulation is digital or not?
Pulse position modulation can be analog or digital, it depends on the signal and/or the modulator used to obtain the modulation. If an analog signal is applied at the input of the modulator, the position of the pulse can assume an infinity of different timing states (the signal vary continuously) and hence an analog modulation is realised in PPM. On the contrary if the signal is digitized previously in a series of discrete states, the pulse at the output will have discrete timing interval (not continuosly). Then a digital modulation is obtained. If the signal is analog, but the modulator is digital, we will have again a number of finite state in output timing, and the PPM will be digital. To be noted that, if the number of steps in the digital modulator, is higher then the dinamic range required, the performance of the digital and analog PPM will be exactly the same. Cecking the front of the pulse of PPM with a digital oscilloscope capable of jitter measurament, we will see immediately if the position of the pulses will be continuosly variable or a number of discrete steps will be presented. We can then consider analog and digital PPM physically different.
Digital pen an output or input?
digital pen is an input device
Is a digital camera an input or a output?
an input.
What is the second step in the pulse code modulation process?
digital converter extracts samples of analog signal from input siganl digital converter quantizes analog sample and assignes a binary numbervalue to it digital coanverter encodes a quantized analog signal to transmit it across a digital network
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
Is a digital camara an input or output device?
Input
How is digital camera an input device?
A digital camera is an input device because it captures information and stores it on the device via the memory card(which is a storage device).
Is modem input or output devices?
Both. Modem stands forMOdulator DEModulater.Modulator comes from modulation which is the process of converting analogue data to digital for transmission and Demodulator from Demodulation, converting digital signals to analogue.Digital data-discrete or non-continuous dataAnalogue data- continuous or non-discrete data
Is digital camera an input device or output device?
Input.
Is mixing the same as amplitude modulation?
No, mixing is adding two signals together, modulation is more like multiplying two signals. IN mixing, the result has the same frequencies as the input signals. In modulation, the result is the sum and difference frequencies.
Is a digital projector an input or output device?
A headset
