A system is sampling a high-frequency signal using an external 16-bit ADC connected to a 5. microcontroller using an SPI bus. The ADC returns a 16-bit sample every time that the SPI bus Poes active. The SPI bus is configured to send 16 bits at a time and runs with a 500,000 Hz clock Determine the maximum sample rate that can be achieved using the ADC connected to the microcontroller using this SPI bus. Assume that the clock must be...

Clock Divider
can i get some simple explanation ( what I'm suppose to

my lecturer explains it but I honestly don't understand what
statements he's trying to make
my understanding :
there's a frequency input of 512 Mhz, since we know 8 bit
counter can count up to 256, it will do it once before it rolls
overload (???)

Computer Architecture
2) (10 points) Consider a microprocessor driven by an 8-MHz input clock, with a 16-bit external data bus. Assume that this microprocessor has a bus cycle whose minimum duration equals 4 input clock cycles. A bus cycle is the number of clock cycles required to accomplish a task (such as data transfer). What is the maximum data transfer rate across the bus that this microprocessor can sustain, in bytes?

We have a microcontroller (MCU) that operates at 3.3V. We want to connect a pushbutton switch to a digital input and a LED on a digital output. The pushbutton is normally open until pressed. The LED has a forward voltage of 2.3V at the operating current of 10mA. We want the input at the microcontroller to go high when the button is pressed. We want the LED to light up when the digital output is low Q5 Explain what two...

1,A MOD 12 and a MOD 10 counter are cascaded. The input clock frequency is 60 MHz. Determine the counter output frequency. 2.What is the output state of a MOD-64 counter after 92 input pulses if the starting state is 000000? 3.What is the frequency factor of a mod 16 counter? 4. How many flip flops are required to design a mod 16 counter? 5. In a mod 10 counter we can distinguish _ different states.

4) We need to send an ASCII code of 0110011 by using a serial communication standard that uses a 250 MHz clock. 4.1) How long will it take to transmit the code including the start bit, the stop bit of 1 clock pulse, and the parity bit? 4.2) And what is the logic state of the serial line 10 nano second after transmission started? Explain by illustrating a waveform for Tx_Data.

Consider a superheterodyne receiver designed to receive the frequency band 1 to 30 MHz with IF frequency 10 MHz. The local oscillator generates frequencies such that the ratio between the maximum and the minimum generated frequency is the smallest. a) What is the range of frequencies generated by local oscillator for this receiver? b) An incoming signal with carrier frequency 6 MHz is received at 6 MHz setting. At this setting we also get interference from a signal with some...
