The minimum bandwidth necessary to pass this signal without excessive distortion is MHz. (Note: to =T*Duty Cycle; T= 1/F) 8- Ten channels, each with a 200 kHz bandwidth, are to be multiplexed together using FDM. The minimum bandwidth of the link is need for a guard band of 10 k Hz between the channels; while the minimum bandwidth of the link is 20 kHz between the channels. KHz when there is a KHz when there is a need for a guard band of 9. If a channel can transmit a range of frequencies from 10 MHz…

Write a program that acquires data from a data source and calculates and displays the Discrete FourierTransform associated with that data. In this case, the Arduino will generate a signal, that is sampled by the ADC and then sent to the computerover the serial port. The  Arduino  code is : int lookup_index = 0; #define SIN_FREQ 100 long sin_freq = SIN_FREQ; #define LOOKUP_ARRAY_SIZE 128UL #define PWM_RESOLUTION 8 #if PWM_RESOLUTION <= 8   #define PWM_t uint8_t #else   #define PWM_t uint16_t #endif PWM_t *lookup_array; // lookup array for sin(2pi f t) PWM_t lookup_array1[LOOKUP_ARRAY_SIZE] = {     127, 133, 139, 146, 152, 158, 164, 170, 176, 181, 187, 192, 198, 203, 208,     212, 217, 221, 225, 229, 233, 236, 239, 242, 244, 247, 249, 250, 252, 253,     253, 254, 254, 254, 253, 253, 252, 250, 249, 247, 244, 242, 239, 236, 233,     229, 225, 221, 217, 212, 208, 203, 198, 192, 187, 181, 176, 170, 164, 158,     152, 146, 139, 133, 127, 121, 115, 108, 102, 96, 90, 84, 78, 73, 67, 62,…
